Enhancement(s):
* For the last couple of years, OpenJDK has used a single build shared among multiple RPMs and a tarball available on the customer portal. The single "portable" build has a release number ('p') and each RPM has its own release number ('r'). However, the RPM naming only showed the RPM release number, while the version output from the build showed the portable release number, making it unclear that they were different numbers. From this release onwards, a release field of the form 'p.r' is always used for RPMs and the version output shows 'p'. (AlmaLinux-212337, AlmaLinux-212338, AlmaLinux-212339, AlmaLinux-212340, AlmaLinux-212342, AlmaLinux-212343)
Bug Fix(es):
* In previous releases, the RPM did not correctly own the subdirectories used for documentation in /usr/share/doc and /usr/share/javadoc. This is fixed in this release, so these subdirectories will be removed when the package is uninstalled. (AlmaLinux-212353, AlmaLinux-212359, AlmaLinux-212360, AlmaLinux-212361)
