Changing EAP 7.4 rpm to java 17

Solution Verified - Updated -

Issue

  • We've previously installed EAP 7.4 rpms to use java 8 or 11. We now want to run EAP 7.4 with java 17. We've installed java 17 but we can't remove java 8 or 11 packages without it also removing other EAP packages. How can we switch EAP 7.4 RPMs to use java 17 so we can also remove the now unused java packages?

  • Uninstalling OpenJDk11 before or after completing the migration (to OpenJDK17) process is removing the JBoss EAP standalone server or become non-functional, leading to significant disruptions.

Environment

  • JBoss Enterprise Application Platform (EAP) 7.4
  • Java 17
  • Red Hat Enterprise Linux (RHEL)
  • RPMs
