      = OpenJDK replaces JVM on IBM Power and IBM Z

      Before this update, Eclipse OpenJ9 was the Java SE implementation for containers targeting IBM Power (ppc64le) and IBM Z (s390x) OpenShift clusters. With this update, the OpenJ9 JVM in the OpenShift containers for IBM Power (ppc64le) and IBM Z (s390x) is replaced by the Red Hat build of OpenJDK. Existing {prod-short} installations, on update to 2.15.1, switch over to use OpenJDK in the Java 8 and 11 sidecar images rather than the OpenJ9 ones. Customers whose devfiles reference the OpenJ9-based containers must edit their devfiles and replace `-openj9-rhel8` with `-rhel8` to continue to receive security updates. See also link:https://issues.redhat.com/browse/CRW-2785[CRW-2785]. Also see link:https://access.redhat.com/articles/6744521[Java Change in Power and Z OpenShift Images].

    Description

      Due to licensing issues, Red Hat can no longer ship openj9 binaries.  z & p architectures had used openj9 due to performance considerations, but will now switch to openjdk (inline with x).

      Changes to be done for 2.15.1:

      • update SSO 7.4 -> SSO 7.5.1 and verify it works for airgap scenarios (CIAM-1269): DONE
      • update operator, devfile and plugin registries to remove swap_images.sh from .sh and dockerfile refs: DONE
      • update java image descriptions (both jdk and j9) to mention Knowledge Base article (see RHMWRT-666): DONE

      TODO:

      • deprecate openj9 images in Comet (CRW-2780)

      CRW 2.15.1 GA is scheduled some time between Mar 1 and Mar 17, subject to QE completion (and the ongoing war in Ukraine).

      See also CRW-2729 for updates to CRW 2.16.

      See also potential future followup work in CRW-2760 for 3.x
