Description Eike Stepper CLA 2011-08-04 02:38:06 EDT 
Cloned from: 353303: RWOLockManager.unlock(CONTEXT) gives ConcurrentModEx
https://bugs.eclipse.org/bugs/show_bug.cgi?id=353303

Unlocking all locks for a given context, i.e. calling 
RWOLockManager.unlock(CONTEXT context), causes ConcurrendModEx,
due to the removal of lockStates while the set of lockStates
for a given context is being iterated over. (The actual
removal happens in #removeLockFromContext.)

No test case was ever written for this scenario. Not sure if
the old RWLockManager did it right. Doesn't matter now, will
provide a fix + testcase for the RWOLockManager momentarily.

Fixed as part of bug 353691.
Comment 2 Caspar D. CLA 2011-08-18 05:33:49 EDT 
Sorry - not fixed in 4.0 yet!
Comment 3 Eike Stepper CLA 2012-06-05 07:29:53 EDT 
Moving all open bug reports to 4.1 because the release is very near and it's hghly unlikely that there will be spare time to address 4.0 problems.

Please make sure that your patches can be applied against the master branch and that your problem is not already fixed there!!!
Comment 4 Eike Stepper CLA 2012-08-14 22:53:25 EDT 
Moving all open issues to 4.2. Open bugs can be ported to 4.1 maintenance after they've been fixed in master.
Comment 5 Eike Stepper CLA 2013-06-29 12:19:04 EDT 
We'll try to address open problems in 4.3 (master) first and then port fixes back to 4.2.
