Features and changes
Binaries and supported environments
Eclipse OpenJ9™ release 0.62.0 supports OpenJDK 27.
OpenJDK 27 with Eclipse OpenJ9 is not a long term support (LTS) release.
To learn more about support for OpenJ9 releases, including OpenJDK levels and platform support, see Supported environments.
ZIP64 extension support is added
OpenJ9 VM now supports ZIP files that use ZIP64 extensions for bootstrap class loading and shared classes cache operations.
This enhancement enables the VM to eliminate the 4 GB size limitation of standard ZIP files and work with large JAR or ZIP files.
The VM automatically detects and handles ZIP files that contain ZIP64 extensions. The VM works with both standard ZIP files and ZIP files that use ZIP64 extensions.
For more information about shared classes cache, see Introduction to class data sharing.
