Released yesterday was the OpenJDK Java 25 release along with Oracle’s GraalVM 25 alternative JVM.
Oracle is supporting Java 25 for the next eight years as a long-term support (LTS) release. OpenJDK 25 brings module import declarations, flexible constructor bodies, and compact source files / instance main methods to make it easier for newcomers to learn Java. OpenJDK Java 25 also worked on the latest Vector API, scoped values, and more.
More details on the many Java 25 changes via the Oracle.com announcement. OpenJDK 25 can be downloaded from jdk.java.net.
A notable removal with the OpenJDK 25 milestone is the removal of the 32-bit x86 port. Per JEP 503, the x86 32-bit port has been removed. The 32-bit x86 source code and build support is now removed after it was previously deprecated back in OpenJDK Java 24. This doesn’t affect x86_64 or 32-bit support for non-x86 architectures.
Removing x86 32-bit support was done due to the port costs outweighing the benefits. In implementing new features and more the ongoing cost of continuing to maintain the x86 32-bit port was deemed too great for what it’s worth.
Also available now is GraalVM Community 25.0 for that JDK with ahead-of-time Native Image compilation along with language runtimes for Python, JavaScript, Node.js, and Ruby. GraalVM 25.0 has more performance improvements to its Native Image mode, including new optimizations by default and more. Plus improved security with “advanced obfuscation” for Native Image mode, for containers and CI environments the build process will now limit itself to 85% of system memory, and various other changes.
