Andrew Dinn commented on JBTM-365:
----------------------------------

"Asynch calls to ...addSynchronization during beforeCompletion" ???

Is there a really good reason for making asynch calls? If so then this raises issues for the asynchronous  addSynchronization client as well as the implementation of beforeCompletion. Specifically, how can you ensure that the asynch calls occur before the end of beforeCompletion processing? Can you please provide more details of what is required here?

> 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.
