Description David Kaspar 2001-11-29 09:52:01 UTC 
This deadlock is hard to reproduce.
It occures after long work of automated tests.
In the attachment there are 3 Full Thread Dumps.

Last time it happened when all automated tests finished and I did these actions:
Expand some filesystem node in the Explorer.
ERROR - Explorer did not show any sub node of this filesystem although in the
directory there was some files.
Close Source Editor window.
ERROR - Deadlock occured

Comment 4 Tomas Zezula 2001-12-04 13:04:39 UTC 
Racecondition in IDLDataObject causes DeadLock of the whole IDE. So,
the priority changed to P2.
Comment 5 Tomas Zezula 2001-12-04 14:50:49 UTC 
The deadlock is caused due to fileChanged after the parse thread
changed  the status of data object to STATUS_OK || STATUS_ERROR and
before the wainting thread in the method getPossibleNames reads the
value of status. This scenerio causes lost of the notification.
Comment 6 Tomas Zezula 2001-12-05 10:42:40 UTC 
Fixed by removing the invalid state from the IDLDataObject.
Comment 7 David Kaspar 2002-04-05 11:46:22 UTC 
Verified - No deadlock occured for a long time.
Comment 8 Quality Engineering 2003-06-30 17:07:41 UTC 
Resolved for 3.3.x or earlier, no new info since then -> closing.
