Re: [qftestJUI] SUT hangs on startup

Hi Dylan,

it's very likely that the startup of your SUT has some small bug where
not everything related to Swing objects is done on the AWT event
dispatch thread. You'll get away with this most of the time, but
qftestJUI often exposes such problems as it causes increased activity
within the SUT and such increases the likelyhood for deadlocks to
happen.

Either way, we need a full thread dump to find out where the cause of
the problem is. Please see message

http://www.qfs.de/archive/qftest-list/2005/msg00092.html

about how to create a full thread dump on Windows.  Best create two or
three dumps (always useful in case there's an endless loop instead of
a deadlock) and send the result to me or the list.

Best regards,
    Greg
