Sebb commented on NET-217:
--------------------------
I can see the same problem on Ubuntu 8.04 (VMWare).
However, if I add a short sleep after the call to tftpS.shutdown(), the problem
goes away.
Even sleep(1) works, but sleep(0) and yield() do not.
This suggests that there is some final tidyup that needs to be done which is
not happening, perhaps because of thread starvation?
Or maybe shutdown() is not waiting for something to complete?
However, a quick trawl through the code does not reveal anything, so maybe it
is a feature of the JVM on Ubuntu?
