The problem with this is that it would make it impossible to get a clean
JDK24/25 test run until all the changes are committed, hence all but the last
commit would be flying blind WRT testing.
(It also wouldn't make a lot of sense, as the changes are exactly the same
for all subprojects)

That sounds better, but I personally don't have the permissions for that.
Could you (or someone else ) open a feature branch and add this commit ?

> 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.
