Foojay Podcast #103: Killing Reflection at Build Time with Dmitry Moskalyuk and Shai Almog

Mon, 19 Oct 2026 00:00:00 +0000

Runtime reflection is one of those quiet taxes on the JVM: it is flexible, it is everywhere, and it is easy to stop noticing it until you go looking for where your CPU is actually going. In this episode, two teams from completely different corners of the ecosystem explain how they went looking and ended up at the same answer: push the work to build time.

Dmitry Moskalyuk is a new author on Foojay. His article “Reflection-Free Serialization on the JVM: Four Formats In, Avro Out” describes a model layer that ingests JSON, XML, YAML and TOML and converts everything to Avro, and the choice between Jackson and kotlinx.serialization that came down to where the reflection cost hides, and where it does not. Shai Almog has been writing on Foojay since 2021 and works on a build-time code generation pipeline for Codename One, with the goal of “no reflection, no service loader, no Class.forName”.

Lottie4J 1.2.7: A Performance Release

Sun, 18 Oct 2026 00:00:00 +0000

A new version of Lottie4J, the Java and JavaFX library to render Lottie animations, is available. Release 1.2.7 doesn’t bring new features, but focuses fully on performance.

Important

USE 1.2.8

The reuse of snapshot images in the matte renderer introduced a regression: animations with track mattes of different sizes could show horizontal streaks during playback (issue #12). This is fixed in Lottie4J 1.2.8, so please use that version instead of 1.2.7.

Pi4J V5.0.0: Work in Progress

Sat, 17 Oct 2026 00:00:00 +0000

What is Pi4J?

Pi4J is an open-source Java library that gives your Java application access to the hardware pins of a Raspberry Pi and other single-board computers. With it, you can blink an LED, read a button, or talk to sensors, displays, and motor controllers over GPIO, PWM, I2C, SPI, and serial, all from plain Java code and without writing any C. The project started more than ten years ago, is now part of the Commonhaus Foundation, and is maintained by a small team of volunteers.

Media Partner for OCX27 and jChampions Conference 2027

Sun, 11 Oct 2026 00:00:00 +0000

Foojay is proud to be a media partner for two very different, but equally great, events coming up: OCX 2027 in Brussels and the fully online jChampions Conference 2027.

OCX 2027

We’re excited to be a media partner of Open Community Experience (OCX) 2027. From 13–15 April 2027, developers, maintainers, researchers, engineering leaders, and open source communities from around the world will meet at Tour & Taxis in Brussels, Belgium.

Featured Foojay Authors for October 2026: Bazlur Rahman and Nicolas Fränkel

Tue, 06 Oct 2026 00:00:00 +0000

Foojay wouldn’t exist without the many contributions from its community, whether it’s a single post or an ongoing stream of knowledge sharing. That’s why we highlight two of them each month as Featured Authors. After Marit and Graeme in September, October belongs to Bazlur Rahman and Nicolas Fränkel. Want to read more from either of them?

Foojay Podcast #102: Why Foojay Walked Away From WordPress for Static Sites

Mon, 05 Oct 2026 00:00:00 +0000

Foojay.io quietly moved off WordPress and onto Hugo, a static site generator. No more CMS login, no database, no admin panel — just Markdown and AsciiDoc files, built and deployed straight from GitHub. In this episode we dig into why that move happened, and into the bigger question behind it: is a traditional CMS still the right way to run a content site in 2026, or has static tooling caught up? Along the way we go through the real security numbers behind WordPress’s plugin ecosystem — more than 10,000 vulnerabilities found in WordPress plugins since 2025 alone — and put very different static site generators head to head: Hugo and Jekyll, the veterans, versus Roq, the Java-and-Quarkus-based newcomer.

JavaFX Links of September 2026

Wed, 30 Sep 2026 00:00:00 +0000

Here are the JavaFX LinksOfTheMonth of September 2026. This was a big month with the release of JavaFX 27!

You can find the weekly lists on jfx-central.com. Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via links@jfx-central.com.

Core

From the OpenJFX mailing list:
- Alexander Zuev integrated 8384483: Create implementation of NSAccessibilityTable protocol, a 585-line addition across 11 files that gives macOS proper accessibility support for tables and lists: “To preserve functionality the separate native peers for tables and lists are created; the list peer for now reports its role as a table for backward compatibility, that can be changed later; fixed the long existed bug where table reported incorrectly currently selected rows.” Reviewed by Andy Goryachev and Ambarish Rapte. PR #2217 — changeset 67853fbf
Gufran Thakur asks on Reddit: “What is the future of JavaFX looking like?” A lot of interesting answers already. Want to add yours? And, thank you Marius Hanl, for mentioning JFX Central in your answer, we appreciate it! :-)
Jose Pereda integrated 8391779: JVM crashes after copy key event on focused WebView that has no selection: “This PR adds a guard to WebKit/EditorJava.cpp, to prevent passing an empty selection to the pasteboard, that would cause an immediate JVM termination, when firing a copy key event over a focused WebView that has no selection.” Reviewed and integrated on 8 September. (PR on GitHub)
Release cycle note: the cutoff for backports into JavaFX 27.0.1 was 7 September, and jfx27u is now open for 27.0.2 fixes — announced by Kevin Rushforth, version bump integrated by Ambarish Rapte on 8 September.
The Release Notes for JavaFX 27 are available in the OpenJFX repository and list everything that went into this release: 7 new features, 20 other enhancements, 77 bug fixes and 6 security fixes.
The Gluon Team published JavaFX 27 is Now Available with an overview of the release: the Metal rendering pipeline as the new default on macOS, conditional stylesheets and media queries in CSS, JavaFX controls in the window title bar, the RichTextArea additions, and over 70 bug fixes and control performance improvements. Two things to check before upgrading: JavaFX 27 is compiled with --release 25, so an older JDK fails at startup, and on macOS you can fall back to the previous pipeline with the -Dprism.order=es2 launch parameter.
JavaFX 27 Highlights lists what is new: RichTextArea tab stop attributes plus embedded image, text background and wavy underline attributes; conditional stylesheet imports; ConditionalFeature and platform media queries; JavaFX controls in the title bar; animations that now respect the reduced motion preference; improved macOS accessibility including navigable static text and hyperlinks; better Flatpak integration through GtkFileChooserNative; and iOS improvements including UIWindowScene support. The community fixed more than 60 bugs, and dependencies moved to WebKit 623.1, GStreamer 1.28.3, libxml2 2.15.3 and libxslt 1.1.45. The highlights page credits Gluon for the bulk of the work on this release.
Andy Goryachev integrated 8390913: RichTextArea: Down arrow stuck on paragraph if space above and below are set: “Fixes broken navigation introduced in JDK-8370902 with non-zero paragraph spacing (above, below, line spacing).” The Rich Editor Demo was also updated to allow setting paragraph line spacing in addition to space above/below (right click → Paragraph). A sizeable change at 539 lines across 11 files, reviewed by Jose Pereda and Lukasz Kostyra, integrated on 15 September. (PR on GitHub, changeset)
Marius Hanl integrated 8392149: Mark deprecated snap methods for removal in SkinBase, a heads-up for anyone writing custom skins: “Since we will remove the snapping methods in Region at one point, we should also do that in SkinBase.” A continuation of JDK-8390773, reviewed by Kevin Rushforth and Andy Goryachev, integrated on 15 September. (PR on GitHub, changeset)
Michael Redlich wrote up the Java 27 release for InfoQ, with a section on JavaFX 27: JavaFX 27 joins Helidon 27 and Jipher 20 as new additions to the Oracle Java Verified Portfolio, delivering a “metal rendering pipeline on macOS for smoother performance on modern Apple hardware”, enhanced text editing controls, and continued accessibility improvements.
Alexander Matveev integrated 8331458: Replace qtdemux with MP4 demux based on Media Foundation in OpenJFX: “Replaced qtdemux with a Media Foundation-based MP4 demuxer on Windows. H.264 video from MP4 and fMP4 (HLS) is now decoded using Media Foundation instead of DirectShow. This change avoids several DirectShow issues encountered with the new MP4 demuxer and reduces implementation complexity.” The changeset also fixes 8305842 (video sometimes does not start when reinitializing on Windows 11). See PR #2206 and commit 67f70684.
Michael Strauß integrated a fix for rows disappearing in a TableView with a horizontal scrollbar: “VirtualFlow stores the scroll location in two values … These two values can become inconsistent … The patch is quite easy: it sets absoluteOffset to zero when all cells fit.” See PR #2317 and the commit.
Public Service Announcement (PSA) from milchshakee on Reddit: starting with JDK 27, you no longer need a separate Main class to launch a JavaFX application from the classpath, per JDK-8248122.

Applications

Former_Weather_1174 made a local music player. “I’ve made a local music player based on JavaFX. Although it’s still quite rudimentary, it already has all the necessary functions. I think some people might be interested in it. Here is the link to the GitHub repository: Kimusic.”
Helal Anwar shared a video of Passport Studio FX, a desktop application to simplify passport and ID photo preparation for local photo studios and print shops. It provides AI-powered background removal with MODNet and ONNX Runtime, manual cropping with passport-size aspect ratios, custom background colors, zoom controls, standard photo size presets, and A4 print-sheet generation with cutting borders. The tech stack is Java, JavaFX, FXML, OpenCV, ONNX Runtime, MODNet, Apache PDFBox, Maven, and jpackage for the Windows build. All images are processed locally, so nothing gets uploaded to the cloud.
LooseCartographer989 announced NumeHub on Reddit, claiming it is “the largest JavaFX application ever built”: “Four years ago I opened a JavaFX project to see how far the platform would go before it broke. It never broke. So I kept going.” NumeHub is a single desktop app that bundles projects, CRM, a point-of-sale system, WhatsApp and email campaigns, a file explorer, a browser and system monitoring, with an AI agent (built on MCP tools) on top that answers questions by voice or text. “Millions of nodes. Under half a gig of RAM. A new release every week.” Runs on Windows and macOS (Apple Silicon and Intel) in English, Portuguese, Chinese and German; Linux is planned if there is demand. It’s not open source and downloads are here. The thread turned into a fun “who has the biggest JavaFX app” contest, with PartOfTheBotnet (9 years, 5,440 commits), _DystopianSnowman (13 years, ~90k LOC) and Siedlerchr weighing in for JabRef.
Thunder_ZEK shared his tiny project on Reddit, Memento: “It’s an application where you are asked 100 questions… about your life, and answers to these 100 questions are basically in depth information about you and your life. So after answering you can download a PDF and share this to anybody.” Built with JDK 17, JavaFX 17, SQLite and OpenPDF, with all data staying on your device unless you export it. The sources are on GitHub. He learned JavaFX from YouTube tutorials and built this over a few months to show he had picked it up - a Windows installer is included, but “it’s only working on my laptop lol.”
The JabRef Team released JabRef 6.0-beta.1, the first beta of the next major version of the JavaFX-based BibTeX/BibLaTeX reference manager. Highlights: almost everything is now navigable by keyboard with visual indicators, a fetcher for Software Heritage identifiers (SWHID), the community themes from themes.jabref.org (Everforest, Nord, Papers, Chocolate Honey and more) selectable from the preferences with preview images, per-tab icons, and automatic reconnection to shared databases. Project on GitHub.
NURI demoed StarLore, a gamified astronomy RPG desktop application: “StarLore is a JavaFX-based desktop application that combines astronomy, mythology, exploration, and interactive gaming.”

Components, Libraries, Tools

Erik Costlow wrote a post on InfoQ about FlexGanttFX going Open Source: “Dirk Lemmerman has open sourced FlexGanttFX, a resource-scheduling framework for generating Gantt charts. Lemmerman open sourced the library after 15 years as a way of increasing availability of the code for use while using the AGPL license as a way to address project maintenance.”
Guilty_Village_958 announced on Reddit that luvml 2.1 is on Maven Central, “a type-safe Java DSL that treats your HTML, CSS, and Vue templates as one typed authoring language instead of three.” The one to watch for JavaFX developers is the sibling project luvjfx, “a terse, type-safe construction DSL for JavaFX”: nested calls instead of imperative setup, with the property methods machine-generated from JavaFX itself by reflection (367 capabilities across 51 node types), built-in one-way and two-way binding, and an escape hatch to the raw JavaFX API. No releases yet, so no Maven coordinates for luvjfx for now.
Chad Preisler needed a sorted list that stays usable at scale: “I needed a sorted list in #JavaFX that could show millions of records in a TableView and still be usable.” The mods project - “New components for JavaFX or enhancements to existing JavaFX functionality” - was created several years ago, but recently got some threading fixes, improved string sorting and usage information in the readme.
Florian Enner published the article behind the video we linked last week: JavaFX 27 as a GraalVM Native Image on a Raspberry Pi 5. It compares Gluon Substrate (still on GraalVM 23 CE and JavaFX 21), BellSoft’s Liberica NIK, and his own StaticFX, which “runs as a regular GraalVM Feature on the stock toolchain” and keeps all JavaFX modules working, including Media and Web. For the AtlantaFX Sampler on a Raspberry Pi 5, the time to the first window drops from 3.6s with jlink to 0.5s, and memory use after visiting all pages from 1,424 MB to 634 MB, in a binary of about 33 MB. The missing reachability metadata remains the biggest hurdle, “but IMO the payoff is worth pushing through the initial barrier.”
Dirk Lemmermann released GemsFX 4.5.0: DialogPane gains a cancellable dialog feature so dialogs can be closed with the ESC key or a dedicated cancel button, the busy button was removed from PowerPaneApp to streamline the dialog options, and SVGUtil now uses a default loader context with jsvg updated to 2.2.0. Project on GitHub.
mkpaz released AtlantaFX 3.0.0, a major update to the JavaFX theme collection: adds window decorations, a Scene Builder plugin, a theme manager, and a new Sidebar component. See the release and changelog.
The Techsenger team introduced PatternFX on Reddit: a framework providing MVC, MVP, and MVVM templates sharing a common architectural foundation. It models a window as a tree of dynamically composable components, each built with one of the three templates, and organizes inter-component communication through type-safe “ports” instead of a bus. Other features include component lifecycle support, component inheritance, history preservation, component-level logging, and an FXML-free design, with a demo implementing the same example in all three templates. Their ShellFX platform is built on top of it.

Podcasts, Videos, Books

Josh Long published two videos on combining Spring Boot, JavaFX, GraalVM native images and Spring Security to build desktop applications: “native, lightning-fast, dynamic, efficient, reusable desktop applications that run well on Mac, Windows, and Linux, and look amazing, while taking small fractions of the RAM of a similar Electron-based application”. Also mentioned in This Week in Spring, September 8th, 2026.
- The Ultimate Desktop Client Stack: Building High-Performance Apps with Spring Boot & JavaFX shows how to use Spring Boot and JavaFX together, “so that you get the component model, event dispatch subsystem, internationalization, lifecycle management, and, of course, the entire and very rich ecosystem of Spring components and can use them to manage JavaFX components, too”, and ends with native image compilation.
- Build Secure Desktop Apps with JavaFX, Spring Boot & PKCE OAuth 2.0 looks at using Spring Security’s OAuth client in the context of a desktop application, “which can not, by definition, hold a client secret”.
Florian Enner published a short video, JavaFX 27 Native Image running AtlantaFX Sampler on Raspberry Pi 5, showing the AtlantaFX Sampler - which uses all controls and nearly all features JavaFX offers - as an ahead-of-time (AOT) compiled JavaFX 27 Native Image created with the latest Oracle GraalVM 25.3: “Everything works, including javafx.media, javafx.web, as well as the desktop integration to open files.” The native image is built with his jfx-static-feature, a GraalVM Feature that statically links the JavaFX native code into a standalone executable, with support for rich text, WebView and media on Windows, Linux and macOS, on both Intel and ARM.
Artistic_Solution117 shared a video of a “Second test of Java-EARTH-GLOBE-1. Pure JavaFX Google Earth / Nasa Worldwind like viewer in a single shot. On-the-fly on the JVM were the agent runs. Built with gemini 3.8 flash with 24-core raytracing and local disk caching”.
Chad Preisler shared a demo video of a pure JavaFX Kafka client: “Check out my Pure #JavaFX Kafka Client application. This project has come a long way since I first showed it. I find it incredibly useful. I hope you like it.” The Visual Kafka (VK) Demo walks through the result on the Chad Preisler YouTube channel. We linked a very early version of this, then still “a very basic Kafka topic viewer”, back in February 2023.

Tutorials

Creating a Simple 3D Platformer Game Using JavaFX is a step-by-step guide by the RottenWiFi Team that builds a playable 3D platformer prototype with a player character, multiple platforms, gravity, WASD movement and jumping, axis-aligned bounding-box collision detection, respawning after a fall, and a goal platform. It starts from a Maven setup and camera configuration and works through frame-rate-independent movement and per-axis collision resolution. The focus is on the fundamentals — scene graphs, coordinate systems and physics — rather than on production tooling, as “JavaFX is a framework for desktop applications with 3D graphics features, not a complete commercial game engine”.

Miscellaneous

Nirvex1 is looking for advice on Reddit while building a desktop Talent Acquisition System with Java 11, JavaFX, Maven, Hibernate and MariaDB: “One of the more challenging parts so far has been managing around 17 different FXML views and connecting all of them properly with their controllers. I also had to spend quite a bit of time understanding module-info.java, resource paths, and how everything fits together in a modular JavaFX application. Thankfully, that part is finally stable.” The questions are about Hibernate session management and LazyInitializationException, how to run database queries without freezing the UI, and which threading patterns and architectural choices keep a large multi-view JavaFX application maintainable. The first answers mostly argue for putting a backend service between the desktop client and the database instead of connecting to it directly.
enthalpyzx started a discussion on Reddit, “How can JavaFX attract more developers?”, from the perspective of someone who hasn’t written a JavaFX application yet but likes what they see: “I’ve noticed that JavaFX is very capable of doing incredible things that I had never imagined.” The open questions are how multiplatform JavaFX really is, whether applications can look native on every desktop (with AtlantaFX mentioned as the likely answer, next to wrappers like Java-GI and QtJambi), why things like tray icons and notifications still need AWT, and above all the lack of a single recommended way of working: “I would like Gluon or Oracle to stand up and say: look, this is how things work now, this is how you work for desktop apps, this is how you work for mobile apps, this is the library you have to use.” Also asked: are The Definitive Guide to Modern Java Clients with JavaFX and Learn JavaFX 17 a good starting point?
indyjoe asked on Reddit for good options to run JavaFX in the browser with minimal rewriting, still allowing a desktop version, supporting a large per-client data model, and scaling to hundreds of concurrent users. The discussion weighs WebFX (promising but limited control support and mostly a one-person project), CheerpJ (good for AWT/Swing, no timeline for JavaFX), Gluon (an old prototype not being updated without funded support), JPro (server-side rendering, a concern for apps with large per-user data), and whether a GraalVM-to-WASM path is even possible.

Diagrams as Code: Mermaid Support on the new Foojay

Thu, 24 Sep 2026 00:00:00 +0000

Some things are much easier to show than to describe. A request travelling through three services, a class hierarchy, the states a connection moves through: a paragraph explaining it takes real effort to write and still leaves the reader assembling the picture themselves.

The usual answer is to open a drawing tool, export a PNG, and drop it in the article folder. That works, and it is what most Foojay articles have done so far. It also means the diagram is now a binary file that nobody can review, nobody can correct a typo in, and nobody can update without finding the original file again, assuming they still have it.

AsciiDoc Support on the new Foojay

Wed, 23 Sep 2026 00:00:00 +0000

Markdown is a good default. It is easy to write, everybody already knows it, and for most articles it is exactly enough.

For some articles it is not. If you have ever wanted to put a caption on a code block, number the interesting lines and explain them underneath, or set a warning apart from the paragraph before it, you have found the limits of Markdown.

Large parts of the Java ecosystem document in AsciiDoc for exactly this reason. So posts here on the new Hugo-driven Foojay, can now be written in it too. Thanks to Brice Dutheil for requesting this feature, and for naming exactly which parts of it he uses. And of course, this post is written in AsciiDoc to show it off!

Announcing The New Foojay

Tue, 22 Sep 2026 00:00:00 +0000

Foojay has moved, but the address stays exactly where it was, just like every URL you have bookmarked, linked or cited. Everything behind that address is new. Foojay is now a static site, its entire content lives in a public Git repository, and publishing an article is a pull request.

If you only read one paragraph: nothing you have written has moved, and nothing you need to do has changed, except if you want to contribute content.

Foojay Podcast #101: Java 27 in Practice: Smaller Heaps, Smarter Defaults, and Valhalla on the Horizon

Mon, 14 Sep 2026 06:11:42 +0000

JDK 27 arrives on 15 September 2026, and it is a feature release rather than a Long-Term Support one. That distinction matters less than it sounds: as Simon Ritter points out, all OpenJDK releases are delivered the same way, and “long-term support” is a property of the binary distributions you install, not of the platform itself. What JDK 27 does have is two changes that switch on by default and cost you nothing but the upgrade. Compact object headers shrink the per-object header from 64 bits to 32, which the JEP measures at a 22% reduction in heap and 8% in CPU on SPECjbb2015 — and because it is internal to the JVM, a JAR you built years ago benefits without a single line changing. Alongside it, G1 becomes the default garbage collector everywhere, including the small, single-core machines that used to fall back to the serial collector.

Azul August 2026 Release: Java's First Monthly CSPU

Fri, 21 Aug 2026 07:48:46 +0000

If someone discloses a 0-day CVE the day after a quarterly update, you could wait up to three months for a patched build. That gap is closed now. The August 2026 release is the first monthly Critical Security Patch Update (CSPU) in Java’s history, and Azul shipped it on schedule across both its product lines.

Core (Zulu Builds of OpenJDK): CSPU builds for Java 26, 25, 21, 17, 11, and 8, with backports to Java 7 and 6. See the Core release notes.
Prime (Zing Builds of OpenJDK): Azul Zing JVM 26.02.310.0 for Java 25, 21, 17, 11, and 8. See the Prime release notes.

This post explains what a CSPU is and what changes about how you plan patches.

Sheetmusic4J 0.0.3: ABC Notation, Guitar Pro, Engraving Improvements

Thu, 06 Aug 2026 08:26:00 +0000

Last week I introduced Sheetmusic4J, a Java(FX) library to render and interact with sheet music. That first 0.0.1 release was really a question more than a product: is there any interest in a native Java(FX) sheet music library before I invest more time in it? So I shared it on social media and waited to see what would come back.

The answers arrived faster than I expected. And they gave me more homework…

" Check the release notes on GitHub.
nlisker shared on Reddit: jextractGUI - A JavaFX GUI wrapper for the jextract tool. “It’s written in JavaFX and embeds jextract (and its libclang) within it. Since jextract is in early-access, newer versions broke it and I needed to do some rewrites since I first conjured it a couple of years ago. It’s now aligned with the current latest build - 25-jextract+2-4 (2025/11/25). " Project is available on GitHub.

Games

Nice Application 1 (Udit) submitted Daybreak Protocol to the DEV June Solstice Game Jam: “A short, replayable JavaFX code-breaking game where daylight is both the player’s timer and reward. Repair six symbolic Bombe relays by solving puzzles based on Caesar shifts, XOR logic, run-length encoding, parity bits, contradiction elimination, and binary search. Every wrong answer visibly pushes the sun toward the horizon. The game celebrates Alan Turing’s legacy by presenting algorithms as creative tools. " Source code on GitHub.

Frank Delporte blogged about a big rendering upgrade for Lottie4J: “My goal was to make the JavaFX output match the official LottieFiles web player as closely as possible, pixel for pixel. … After the improvements, most of the animations used in the test now hit 99.5%+ similarity with the reference!”
Frank Delporte released Lottie4J v1.2.5 with many rendering accuracy fixes: “The JavaFX animations are now more closely aligned with the official LottieFiles web player. Most test files reach the 99,5% similarity goal. " All info on the website.
Dirk Lemmermann is reworking/improving his libraries: “I fixed a major bug in HiddenSidesPane that prevented proper layout passes for children nodes. To get the fix start using the implementation found in GemsFX, do not use the one in ControlsFX. (btw: I moved several of my ControlsFX contributions to GemsFX in order to speed up development.)”
rrangelox published GrooveFX: Dynamic FXML for JavaFX, declarative iteration, conditionals and branching. “I’m releasing GrooveFX, a small library that extends JavaFX FXML with declarative control structures: iteration, conditional rendering, and multi‑case branching directly inside FXML. The idea is simple: FXML is powerful but static — GrooveFX adds flow without replacing it and without introducing a DSL. " Check the Codeberg repository.
Frank Delporte announced a new JavaFX library: Sheetmusic4J, an open-source Java library that parses MusicXML into Java objects and renders them as native JavaFX music sheet views. No WebView, no browser engine, no JavaScript bridge.
- Website: sheetmusic4j.com
- Source code: github.com/sheetmusic4j/sheetmusic4j
- Blog post and video with more info about the project on webtechie.be.
Frank Delporte blogged about Sheetmusic4J 0.0.3: “I released 0.0.1 as an open question: does anyone want a native Java(FX) sheet music library? Multiple LinkedIn comments, and some are answered now with support for ABC notation and Guitar Pro. Plus a big round of engraving improvements.”
Eliezer Assunção De Paulo announced Megalodonte, a small reactive UI framework on top of JavaFX. “I’ve been building JavaFX desktop apps for a while and got tired of the usual boilerplate (manual listeners, imperative styling, no real component model), so I built Megalodonte: a thin reactive layer on top of JavaFX — React-ish component composition, State /ComputedState for reactivity, and a Props/Theme system so styling isn’t scattered setStyle() calls everywhere. " The project is available on GitHub.
Dirk Lemmermann shared: “GemsFX 4.3.2 is out now with fixes for the PopOver control, with i18n resource bundles, and accessibility support. I was always too lazy for the last two things but with AI that has become a no-brainer … literally …. “no brain required”. " Check the project on GitHub.

Introducing Sheetmusic4J, a Java(FX) Library to Render and Interact with Sheet Music

Thu, 30 Jul 2026 07:28:00 +0000

I’m building MelodyMatrix with my son, an application to look at and play along with music. The app already shows a song in different views: falling blocks, chords, guitar views, and many more. Now we want a Learn section, a view that helps someone practice piano by following the actual sheet music while it plays.

A static PDF of the sheet doesn’t work for that. Great PDF viewer components exist for JavaFX, but a PDF has no connection to what’s playing. Nothing highlights the current note, nothing marks the current position in the song. I looked for a JavaFX library that renders sheet music and lets code interact with it: jump to a position, highlight a note, follow playback. I couldn’t find one, so I built it.

We kicked this off in July with Igor and Steve, and this post covers both our July and August (Cristobal and Shai) featured authors. Want to read more from any of them? Just click their name to visit their Foojay author page, where you’ll find their full list of posts. We’ll be back with the next update at the beginning of September.

New Between-Quarters Security Updates for Java: What CSPUs Mean for Your Release Pipeline

Mon, 27 Jul 2026 07:31:11 +0000

In an announcement on the OpenJDK Updates Mailinglist on July 20, 2026, Rob McKenna explained a change in the Oracle security release cycle for JDK builds. They plan to deliver security updates for the Oracle JDK as part of (some) monthly Critical Security Patch Updates (CSPUs) .

This brings more exact info, after an earlier message on April 26, 2026, in which Oracle announced the acceleration of Vulnerability Detection and Response. In that article they introduced the idea of monthly Critical Security Patch Updates (CSPU) across all their products. At that moment, it was not clear if this also applied to the Java releases, and how this would impact the normal quarterly cycle of Critical Patch Updates (CPUs).

Azul Zulu July 2026 Quarterly Update Released

Thu, 23 Jul 2026 12:35:26 +0000

Every three months your production JDKs fall further behind on security patches. Azul closes that gap today with the July 2026 quarterly update for Azul Zulu Builds of OpenJDK, covering Java 26, 25, 21, 17, 11, 8, 7, and 6.

The Quarterly Update Cycle

Every three months, in January, April, July, and October, the OpenJDK project ships security patches, bug fixes, and improvements for all supported Java versions. This predictable schedule lets teams plan Java updates and keep production environments secure.

First Test of Java on Banana Pi (ARM and RISC-V), Plus a Blinking LED with Pi4J

Mon, 20 Jul 2026 06:03:00 +0000

As part of my 2026 learning goals around Java on RISC-V (see this post about x86 versus ARM versus RISC-V), I’ve asked various suppliers to send me evaluation boards. I already published these:

LattePanda IOTA (x86)
OrangePi 5 Ultra (ARM) and OrangePi RV2 (RISC-V)
VisionFive 2 Lite (RISC-V)
BeagleBoards (ARM and RISC-V)
Java 25 on BeagleV-First
In this post: Banana Pi’s

I got all these boards for free, but what I write here and show in the video is not controlled by the suppliers.

Foojay Podcast #100: Java Podcasters on Why They Started, What Broke, and What They Learned

Mon, 13 Jul 2026 07:05:59 +0000

Foojay Podcast hits episode 100. No plan, no roadmap. It just happened. To mark the occasion, Frank turned the microphone around and invited other podcasters: Adam Bien (airhacks.fm), Jennifer Reif (Breaktime Tech Talks), Kadi McKean and Steve Pool (10xInsights), and Oumaima Zerouali (JCast). Same three questions for each: why did you start, what broke, and what did you learn?

Closing the Visual Gap Between the Official Lottie Webplayer and Lottie4J

Tue, 07 Jul 2026 08:25:55 +0000

A Lottie library is only as good as its output looks. If an animation renders differently in Lottie4J than it does in the official web player, that’s a bug, even when no exception is thrown and the code looks correct.

Within the fxfileviewer, there is an app to visually compare the result of the JavaFX player and a webview using the official JavaScript player. Problem is that I was using the JavaFX Web component for this and this doesn’t fully support the latest/best version of this player. Based on this app for manual checks, I also created a unit test which is able to loop over a set of files and compare the differences to make sure changes in the code don’t break the existing renderer. But I kept struggling with the same test file interactive_mood_selector_ui.json which didn’t render correctly, both in the JavaFX view and my web-based view to compare it with.

A Week of Housekeeping: What Changed on Foojay.io

Mon, 06 Jul 2026 10:04:00 +0000

Running a community website is a bit like maintaining a codebase: the content that matters most is never completely done. And if you don’t schedule regular housekeeping, things can get outdated… Last week, we did some cleanup, restructuring, and updating. Here’s an overview of what changed.

The top menu needed some restructuring…

The News menu now focuses purely on what it says: Daily News, the Foojay Podcast, the JC-AI Newsletter by Miro Wengner, the new Foojay.io AI Portal, and the Event Calendar. The AI Portal is a recent addition we hadn’t properly surfaced before. It collects AI-related resources and tooling for Java developers, so it deserves its own slot in the navigation.

JavaFX Links of June 2026

Tue, 30 Jun 2026 07:23:31 +0000

Here are the JavaFX LinksOfTheMonth of June 2026. You can find the weekly lists on jfx-central.com. Did we miss anything? Is there anything you want to have included in one of the next overviews? Let us know via links@jfx-central.com.

Core

Message by Johan Vos: “I’ve spent most of today (and the past few days) on JavaFX 17/21/25 LTS. It’s a lot of work, but almost a pleasure because the tools/procedures are so clear. Skara is extremely helpful with backports. And it’s deterministic. JavaFX is very well maintained.”
From the dev mailinglist: Michael Strauß integrated JDK-8385459 in PR #2177: Animations should respect reducedMotion preference: “Several JavaFX controls use animations to convey state changes, but none respected the reducedMotion accessibility preference. This change makes TableRowSkinBase, TitledPaneSkin, TabPaneSkin, PaginationSkin, and Charts honor Scene.Preferences.reducedMotion.”
Apparently, the JFX Adopters Meeting 2026 led to a pull request by Marius Hanl in the OpenJFX repository: 8386663: Stylesheet/StyleClass list should be lazily initialized. Thanks, Oliver Kopp for sharing this info.

Applications

Video by Ethan Lee: “I Built My Own Agentic AI Browser Turtlebrowse now with Java CEF, Swing, and embedded JavaFX components. Go watch it on YouTube.”
Ethan Lee released Turtlebrowse v1.1.1, the open-source browser built to be agentic: “This brings features like a multi-process architecture and custom profiles. It also brings patches for internal API errors. It uses Gemma4 under the hood, perfect for everyday tasks. Get it at turtlebrowse.ingstudios.dev!”
Gufran Thakur created a simple, minimal Canvas Application in JavaFX: “After like a year finally getting back to JavaFX, decided to make an excalidraw inspired app for fun. It’s a very minimal canvas app with basic features. Source code is on ExplainFX. Features: Drawing, Create Squares and Circles, Text, Vary stroke size/font size,… Please let me know if you have any questions!”
Max Xiong continuous his “Building In Public” journey for his DataCollie application. Follow him on Bluesky for regular updates and screenshots: “Tonight I implemented the custom UI styling for Project context menu items.”
Found on Reddit, by xdsswar: “Dropping a small PDF viewer for you guys (JavaFX + native PDFium). It’s done on native PDFium via Java’s FFM API (no PDFBox, no AWT). Has zoom, text selection, search, thumbnails, the usual, would love some feedback. Repo link.”
By RGiskard7: “I built Jylos, a local-first open-source knowledge management app using Java and JavaFX. It started as a personal project to explore desktop application architecture, JavaFX, Markdown processing and software design. Over time it evolved into a complete application with: Markdown notes with live preview, Wiki-links and backlinks, Interactive knowledge graph,… Everything is stored locally. No accounts, no cloud backend and no telemetry. The project is open source under the MIT license and binaries are available for Windows, Linux and macOS. I’d really appreciate any feedback, especially from JavaFX developers.”
Mechanical-pasta shared his “First JavaFx Application” on Reddit: “I tried JavaFx, and, as a support project to learn the language, I’ve decided to build my own MineSweeper but with some differences. You can find it here if you’re interested.”
In the Links Of The Week of 2026-05-29, we shared “DiskSpace”, a cross-platform disk space visualizer by Marcus Hirt . In the blog post Using GraalVM, JavaFX and a Clanker to Build a Cross Platform Desktop App, he shares a lot of background information about the project, the architecture, and the build process.

Components, Libraries, Tools

Striking_Creme864 shared a video on Reddit: “Live property editing for JavaFX nodes in DevTools. When building JavaFX applications, we often need not only to inspect a node’s properties, but also tweak them to see how they behave. Restarting the app every time to test small changes quickly becomes a major time sink. So we added live property editing directly to the DevTools in our platform (TabShell). The property editor supports three simple forms: basic values, enums, and Insets, but this made UI debugging and iteration much faster.”
Dirk Lemmermann shared screenshots of the new StageStyle.EXTENDED: “I recently updated the FlexGanttFX showcase application to use the new HeaderBar component and StageStyle.EXTENDED type. This results in a very clean and professional looking UI. "
- You can also try it online at demos.jpro.one/flexganttfx-showcase.html or install locally via jdeploy.
Frank Delporte released Lottie4J 1.2.4: “Fixed Lottie arc rendering: constrained the easing solver to prevent bezier curve divergence. Added bisection fallback for flat-point curves. Fixed full-circle trim path flickering caused by floating-point precision loss in offset wrapping. Fixed border rendering error. Added Pi4J test file. " Available on Maven Central.
FXML/2 for JavaFX: IntelliJ IDE plugin for the FXML/2 markup format, supporting syntax highlighting, folding, formatting, EditorConfig-aware indentation, tag and attribute resolution, code completion, and navigation to JavaFX classes. Presented as “FXML 2.0: Write Markup, Ship Bytecode” by Michael Strauß at the JFX Adopters Meeting.
Jonathan S. Fisher is working on DiFX, a CDI / Dependency Injection For JavaFX: “The goal is to have CDI backed beans and events inside JavaFx Desktop Applications. I could use a few eyes/ideas before I cut an initial release and stabilize the API.”
techsenger published ShellFX on GitHub: a platform for building JavaFX applications using an extended MVP pattern. Part of the growing Techsenger JavaFX library ecosystem (alongside CEFFX, TabPanePro, PatternFX, StagePro, etc.).
FX Flow 0.6.1 got released: declarative, fluent UI library for JavaFX. Adds validation support for atomic multi-value updates. More info by john16384 on Reddit/r/JavaFX.

Podcasts, Videos, Books

Frank Delporte published a blog and video: “Lottie4J started as a single question: can JavaFX render Lottie animations without a WebView? That question turned into a library. The library attracted pull requests. And now I had a 50-minute conversation with Naail Abdul Rahman, R&D engineer at LottieFiles, to talk about where the format is heading and what that means for a Java implementation.”
Pedro Duque Vieira shared a video on LinkedIn: “New capability added to the IKE Knowledge Layout Editor: display semantics can now be viewed in a table format. This provides a more structured way to inspect semantic information, which can be especially useful when working with large numbers of semantics.”
A live session of 2,5 hours with Johannes Rabauer and Anton Arhipov : Building a MIDI Visualizer with Junie, IntelliJ and JavaFX: “AI assisted development is becoming a core part of modern software engineering. But what does that actually look like in a real Java project? In this live coding session, we explore AI powered development inside IntelliJ IDEA while building a JavaFX application that visualizes MIDI music through animated waveform based visualizations. Rather than treating AI as a code generator, we will use Junie and other IntelliJ AI capabilities as development partners throughout the process. Together, we’ll explore how AI can help with architecture, implementation, refactoring, testing, and day to day development decisions.”
Frank Delporte interviewed David Gutierrez in a new video: JavaFX In Action #27 with David Gutierrez about JMathAnim to Create Mathematical Animations: “JMathAnim is a Java library and UI built on JavaFX that lets you create animated mathematical visualizations. The goal is simple: make it easy to build videos that explain mathematical concepts through animation. It’s inspired by the kind of content you see on YouTube channels like 3Blue1Brown.”

AI-Assisted Unused & Dead Code Removal

Sun, 28 Jun 2026 07:19:42 +0000

Why Your Codebase Is Forcing AI to Underperform, and What to Do About It

Your AI coding assistant is only as good as the codebase it works on. If your Java application carries years of dead & unused code, and most do, the AI spends its reasoning budget on code that nobody runs. The result is more hallucinations, worse suggestions, and higher token costs. Here’s what to do about it.

Systematic AI Coding: My Takeaways from the Eclipse Foundation Workshop in Brussels

Tue, 23 Jun 2026 19:48:42 +0000

Most developers using AI tools are still guessing. The Eclipse Foundation’s first AI Coding Workshop in Brussels was built to change that. It’s a brand new format they launched in Brussels, which makes sense: most of the Eclipse event team is based there. They plan to bring it to more cities from here, so keep an eye out if you want to attend such a workshop in the future. They offered 10 free tickets to share with the BeJUG and Foojay community. And in all honesty, I used one for myself. Jonas Helming from EclipseSource led the workshop, with a fun quiz hosted by Thomas Froment in the afternoon. Here’s what I took away.

Foojay Podcast #99: Testing the Untestable: LLM Security for Java Developers with Tiberius

Mon, 22 Jun 2026 06:54:00 +0000

Your AI-powered Java application is live in production. But have you actually tested whether it can be jailbroken or manipulated into leaking data it should never reveal? In this episode, Iryna Dohndorf walks us through Tiberius, an open-source security testing library for LLM applications in Java, and explains why everything you know about unit testing needs a rethink when non-determinism is part of the design.

Building Java Containers Without a Dockerfile: Azul Zulu and Paketo Buildpacks

Thu, 18 Jun 2026 08:15:45 +0000

This is the 5th post in the Azul Zulu Docker Official Images series:

Every post in this series so far has shown you a Dockerfile. You pick a base image, copy a JAR, set an entrypoint, and ship. That works well. But Spring Boot developers often skip the Dockerfile entirely and still get a production-ready container with Azul Zulu as the JVM thanks to Paketo Buildpacks. Here is how that works, and how to configure it.

Foojay Podcast #98: The End of JNI Pain: How WebAssembly Is Quietly Replacing Native Libraries in Java

Mon, 15 Jun 2026 08:13:00 +0000

WebAssembly is already running inside Java applications, most developers just don’t know it yet. In this episode, Andrea Peruffo walks us through how WebAssembly is becoming the modern, safe alternative to JNI: letting you run Rust, C, and other native libraries directly on the JVM, without the crash risks, the per-platform distribution headaches, or the observability blackhole that JNI creates. From JRuby’s Prism parser to SQLite and Postgres running as pure Java bytecode, the use cases are real and the project Endive, under the Bytecode Alliance, is ready to explore.
