[jira] [Created] (HBASE-29728) Support Java 25

Istvan Toth created HBASE-29728:
-----------------------------------

             Summary: Support Java 25
                 Key: HBASE-29728
                 URL: https://issues.apache.org/jira/browse/HBASE-29728
             Project: HBase
          Issue Type: Improvement
            Reporter: Istvan Toth


Hadoop trunk now supports Java 25, and is planning to backport it and release 3.4.3 with JDK25 support.

We can start working on Hadoop 3.5 support now, or wait for the next official Hadoop release with Hadoop 25 support JDK25 in HBase.

The Subject changes will be hopefully handled by the UGI changes, but we will have to 
* duplicate the SubjectInheritingThread mess
* Remove SecurityManager usage
* Fix all the smaller incompatibilities
* If going with 3.5, then solve any Hadoop API incompatibilities
