Pavel Kadlec commented on JBTM-365:
-----------------------------------
I do not understand why you synchronize access to variable _synchs each time on different variable. Against variable this, _synchs, and _syncLock. Is it plan? I am not sure. I can not see all conseruences, but it looks strange.

> Asynch calls to com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.addSynchronization during beforeCompletion are problematic since access to _currentRecord and _synchs is unsynchronized in addSynchronization wrt beforeCompletion. This is similar to JBTM-188.
