+1 for JDK21 tests and formal support , happy to provide a hand there. JDK21 generational ZGC is particularly attractive

While JDK 22 has hard breaking changes, and support for Java 22+ is dependent on Hadoop (hopefully the upcoming 3.5.0 release), I am not aware of major breaking changes between Java 17 and 21. IMO we should add Java 21 tests (and fix any issued found) to our Jenkins test and start formally supporting it in Hbase. WDYT ? Istvan.
