Eclipse OpenJ9 0.37 Released - But It Shouldn't Be Used In Production

A new release of Eclipse OpenJ9 is now available, the high performance JVM implementation previously developed as IBM J9.

OpenJ9 continues developing new features and improvements for this open-source, high performance Java Virtual Machine. With the OpenJ9 v0.37 release they are now using GCC 11.2 as their reference compiler on Linux compared to GCC 10, added support for the com.sun.management.ThreadMXBean interface, various AArch64 fixes (including macOS AArch64 support being new), and a variety of other minor improvements and fixes.

But Eclipse OpenJ9 0.37 isn't recommended for use in production. Due to the timing of the release and the OpenJDK cycle, this release carries the following warning:

"Eclipse OpenJ9™ release 0.37.0 works with OpenJDK 19. OpenJDK 19 is out of support at the time of the 0.37.0 release. Builds of 0.37.0 should not be used in production and might contain known security vulnerabilities as of 18 April 2023."
