Joining a dead thread

[Brian J. Sayatovic]

What happens if you call Thread.join() on a Thread that is already
dead? The JavaDocs (from 1.3.1, which I'm stuck on for now) don't
specifically say. I hope that the result is that join() just returns
immediately, as that is the intention of join() -- to make one thread
wait while another one is still busy.

Regards,
Brian.

Yes - it's an immediate return.
