In theory, that's what Thread#interrupt is for. It asks the thread to shut
down, resulting in setting the #interrupted flag / an InterruptedException
on potentially blocking calls such as wait() or sleep(). One could
interrupt named jsp like that.

However, dealing correctly with InterruptedExceptions is hard (you should
leave your objects in a meaningful state) and since InterruptedException
also is a checked exception, many people choose to
catch(InterruptedException ie) {}, even(?) Sun ORB code does so (not to
speak of my own).

Those threads are inevitably lost.
