Well thanks, but I'd prefer monitor-side hook. App-side hook has at least these 
disadvantages:
- the app would have to get root privileges to run jstack
- the app might hang so well that even its shutdown hooks won't work.

Besides, I can't see how to distinguish a normal shutdown from a Force Quit — 
we want jstack in the latter case only.

Nevertheless, if there's no other way, it's definitely a way. Thanks!
