Security Fix(es):

• JDK: Enhance array handling (CVE-2025-21502)

Important Changes:

• The Red Hat build of OpenJDK 17 is now the default system-wide version of Java on Red Hat Enterprise Linux (RHEL) 9, because the full support phase for Red Hat build of OpenJDK 11 has ended (RHEL-63035, RHEL-63036).

The 11.0.25 release was the last release of Red Hat build of OpenJDK 11 from Red Hat in the full support phase of the lifecycle. The full support phase for Red Hat build of OpenJDK 11 ended on 31 October 2024.

As a consequence, Red Hat build of OpenJDK 17 will be the default system-wide Java version on RHEL 9 after 31 October 2024.

Please refer to the Release Notes for Red Hat Build of OpenJDK 11.0.25 [1] for more details, including the Extended Life Cycle Support (ELS) phase for Red Hat build of OpenJDK 11 and for migration instructions.

See [2] for instructions on configuring Red Hat build of OpenJDK 17 on RHEL and selecting the default Red Hat build of OpenJDK version to use system wide.
