Description Jan Zajicek 2002-01-21 12:44:39 UTC 
jdk1.4.0-rc-b91
3.3.1 build #200201210331 (RC2)

A deadlock occured while running overall validation test suite (when switching
between projects). The same deadlock was reported when running CORBA validation
tests. Seems like not 100% reproducible. Full thread dumps follow.

Accepted...
Comment 4 David Kaspar 2002-01-21 15:42:43 UTC 
I could reproduce this bug when I am running CORBA validation tests.
It happens cca once per 10 runs.

proposed fix.
Comment 6 David Simonek 2002-01-21 17:39:52 UTC 
It is fixed in main trunk. Synchronization repaired between component
container implementations. SplitContainerImpl and
MultiTabbedContainerImpl was erroneously synchronized on the same lock
as DefaultContainerImpl.

David, please test against main trunk tomorrow.
I wouldn't put this fix into 331 as the fix itself is not that simple
and I'm not sure whether this can have some side effects or not
Comment 7 Jan Zajicek 2002-03-25 13:17:07 UTC 
I haven't seen this anymore, after fix was applied.
Comment 8 David Simonek 2002-03-26 09:51:26 UTC 
*** Issue 21867 has been marked as a duplicate of this issue. ***
Comment 9 Peter Zavadsky 2002-03-26 11:09:27 UTC 
I reviewed the fix (including the last in MultiTabContainer...), and
think it is surely better and saver way than before.
I would put it in.

Note:
Also I want to mention this fix probably solves issue #21823 too.
Comment 10 David Simonek 2002-03-26 14:28:04 UTC 
Merged into orion_fcs branch.
Comment 11 Jan Zajicek 2002-03-27 10:45:56 UTC 
Also verified in FFJ40.
Comment 12 Quality Engineering 2003-07-01 16:29:09 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
