Hi Seyvet,

If you look at those two stack traces you can see a common line:

at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.afterCompletion(TwoPhaseCoordinator.java:402)

The only ordering that can be guaranteed is for interposed synchronizations (registered by the TransactionSynchronizationRegistry):
 http://docs.oracle.com/javaee/5/api/javax/transaction/TransactionSynchronizationRegistry.html#registerInterposedSynchronization%28javax.transaction.Synchronization%29 http://docs.oracle.com/javaee/5/api/javax/transaction/TransactionSynchronizationRegistry.html#registerInterposedSynchronization%28javax.transaction.Synchronization%29

There was a little mistype in my original response which I will now refactor in the original to say:

...
foreach ResourceManager
   rm::commit()
foreach InterposedSynchronization
   s::beforeCompletion();
foreach Synchronization
   s::afterCompletion();

i.e. When it comes to afterCompletion, interposed synchronizations will be called *first* which is one way (if you only have two synchronizations  ;)  ) to guarentee order.
