You can't cause other resources to not commit in this case.  E.g., prepare succeeds, but during commit, something goes wrong (e.g., network failure).  With a Sync infinispan is only called with an afterCompletion() which is too late to inform other resources of a failure.  But an XA commit() means the TM can inform other resources and attempt a recovery with these other resources.
