> Java 22 breaks Subject propagation for new Threads (when SecurityManager is not enabled).
> Previously, the Subject set by Subject.doAs() / Subject.callAs() automatically propagated to any new Threads created (via new Thread(), not Executors).
> With JDK22, this is no longer the case, new Threads do NOT inherit the Subject.
> As Hadoop heavily relies on the original behavior, we somehow need to solve this problem.
