Thank you for your suggestion. Yes, queryTermination should be a place to
set up some status changes. And real stop or shutdown a process should be
done in notifyTermination. BTW, I saw that there is a XTerminationListener2
where cancelTermination() is called when the master environment (e.g.,
desktop) was canceled in it's terminate request. Is it good to use this
interface?

Is there a bug report number regarding this issue? I would like to check its
progress in the future. In addition, since notifyTermination is also
protected by SolarMutex, I am wondering if you see any workaround to deal
with such a deadlock issue related to multithread shutdown.  Thank you.

Best,
