With java-11-openjdk moving to extended life support (ELS), we should populate the repositories and make sure all processes are in place before the first ELS only update in January 2025.

There are also still a few clean-up changes that need to be made to complete the transition:

• The java-11-openjdk package in the base RHEL buildroots will no longer be updated with future security updates. We should switch the JDK to use its own in-tree timezone data, so that future timezone updates do not break the obsolete JDK. System timezone data will still be used by the ELS java-11-openjdk so we should populate those repositories with a version of java-11-openjdk prior to the removal of system timezone data.
• The java-11-openjdk package in the base RHEL supported a greater number of architectures than ELS will. We should only build ELS on supported architectures.
• There is no java-17-openjdk package on x86_32 so the move to make it the default there should be reverted in base RHEL, so something still provides 'java', etc.
