Extending Availability of IBM Semeru Runtimes V11 Beyond October 2024

September 14, 2023


IBM has extended the availability of IBM Semeru Runtimes V11 from Oct 2024 to Nov 2026. Semeru Runtimes is IBM's build of OpenJDK with Eclipse OpenJ9 technology. The IBM Semeru Runtimes support page (which includes downloads) is now updated to reflect this additional two years of availability for Version 11.

What is IBM Semeru Runtimes?

IBM Semeru Runtimes is a free distribution of production-ready binaries built with the OpenJDK class libraries and the Eclipse OpenJ9 JVM.

What's changing for Semeru Runtimes V11?

By extending the availability of Version 11, IBM will continue to release security and bug fix updates on a quarterly cadence until Nov 2026, publicly and with no cost.

If you are an IBM customer with entitled support for IBM Semeru Runtimes V11 through another licensed IBM product or through IBM Runtimes for Business, you can also continue to raise support tickets and receive defect fixes where appropriate.

Why is this changing?

Previously, IBM Semeru Runtimes was available until Oct 2024, in line with the availability of OpenJDK Java 11 ending in Oct 2024. However, recognizing that there has been significant change in the delivery cadence of Long Term Support (LTS) Java releases, IBM understands that many users have only recently migrated to Java 11 or are in the process of doing so. With the Oct 2024 end of availability for OpenJDK Java 11 fast approaching, not all users have had enough time with Java 11 before they need to start planning their transition to a later LTS release.

What should I do if I use V11?

While IBM encourages all users to move to the more recent LTS versions of Java that are now being released every two years, this availability extension announcement for Semeru Runtimes V11 gives users an extra two years to help plan and implement a smooth transition from V11 to the latest versions of IBM Semeru Runtimes.
