@stoty , @pan3793 , Honestly, I do prefer adding a builder instead of having
multiple constructors with different parameter combinations. Also, a builder
can build subclasses but constructors can't.
In addition, extending the `Thread` class is not a good practice

> 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.
