I'm not sure I understand how this stack trace is occurring. Is it
possible that there's an error in Harmony exception handling? Here's
what's supposed to be happening here. At ORB shutdown, the socket that
acceptor has issued the accept() call is closed. That's line 111 in
Acceptor_impl. This should cause an I/O exception, which is what the
stack trace is showing. However, there's a catch for that IOException
at line 125 in Acceptor_impl that should be turning that into a
org.omg.CORBA.COMM_FAILURE exception. That exception in turn should be
caught GIOPServerStartedThreaded.starterRun(), which detects at that
point that this is a shutdown situation and terminates the run loop on
the thread. The loop that Jarek mentioned in ORBControl is waiting for
the server threads to finish shutting down, but if that IOException is
not getting trapped properly, this thread goes away without cleanuing up
its state. I am a little puzzled about how completeServerShutdown can
get caught in a loop, since it appears to have a cap on how many times
it will go around that loop.

Hi, all,
I observe the following stack trace when shutting down Geronimo
(branches/2.0) running on Harmony, and then Geronimo stops responding
forever.
Otherwise, Geronimo runs pretty well on Harmony, see [1], details are at
[2].
What is interesting is exactly similar stack and hang are observed when
running org.apache.geronimo.yoko.TSSConfigEditorTest test on Harmony, I
already wrote about it, see [3].
For now I couldn't find out the cause for this behavior, so if someone
has any ideas on where to look, I'd be grateful. Thanks!
