Why Upgrade?Upcoming Webinar: Your Migration Guide

JDK 25 has arrived as the latest long-term support (LTS) release for Java, bringing performance improvements and enhanced stability for modern applications. If your organization is running JDK 21, now is the time to start planning your migration path.

Why Upgrade?

Each new LTS release represents years of refinements, optimizations, and new capabilities. JDK 25 builds on the foundation of JDK 21 while delivering the reliability that enterprise applications demand. But understanding what's changed—and what might break—is essential for a smooth transition.

Upcoming Webinar: Your Migration Guide

Azul is hosting a live session, led by Java Champion Simon Ritter, covering everything you need to know about moving from JDK 21 to JDK 25. The webinar will cover key differences between the two releases, new features and compatibility considerations, and best practices for a seamless migration.

Attendees will also see a live demo of an example application migration, along with alternative approaches for upgrading to Azul's Zulu build of JDK 25.

Session Times:

  • NAM: January 27th at 10:00 AM PT / 1:00 PM ET
  • EMEA: January 27th at 12:00 PM UTC
  • APAC: January 28th at 12:00 PM SGT

Whether you're just starting to evaluate JDK 25 or ready to begin your upgrade, this session will provide practical guidance to help you move forward with confidence.

7 Ways to Contribute to OpenJDK

In this article I outline 7 possibilities, ranging from minimal work (because you’re too busy to do much, but you’d like to do something) to intensive work (participating on OpenJDK development is everything you want to do, it’s more than a hobby, you want to contribute to the maximum extent possible).
