In case you are wondering, like me, what's the point here is some quote from the linked release "The difference for the user is minimal, but for maintainability the upstream alignment with both OpenJDK 11 and GraalVM is critical. It means that Red Hat can offer better support to customers since we have skilled engineers working within the OpenJDK and GraalVM community." So basically RedHat is building this so they have a stable basleline for their Enterprise releases.
