Bug Fix(es):

• In the previous release in October 2023 (8u392), the RPMs were changed to use Provides for java, jre, java-headless, jre-headless, java-devel and java-sdk which included the full RPM version. This prevented the Provides being used to resolve a dependency on Java 1.8.0 (for example, "Requires: java-headless 1:1.8.0"). This change has now been reverted to the old "1:1.8.0" value. (RHEL-19634)
