That looks like it could work @szetszwo .
There is still the issue that if there is any logic in the wrapped Thread's
start() method, then it won't be run,
but we can document that (and the current SubjectInheritingThread also makes
that final, so we know that none of the Threads in Hadoop does that)

> 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.
