Review Comment:
I realized (doing the code) that awaitTermination requires that
shutdown/shutdownNow has been previously invoked , otherwise will NOT work as
expected . So when executor is provided, after PersistentTTLNode has been
closed I will wait for 100ms and check that executor there is still there
Maybe looking for the thread using the threadId and the name is a bit too
much, when it is enough to check if the executor isShutdown or NOT.
I will provide commit that is able to check if excutor is shutdown in both
cases, and also the thread checks and you provide comments. Now I am more in
favour to remove all the code that looks for the thread from stacks traces, BUT
just give me your opinion there
