UnsupportedOperationException is thrown when persist + flush + dirty entity + commit

Steps to reproduce:

1. Start a JTA transaction
2. Persist an entity that uses transactional cache concurrency strategy
3. flush the entity manager
4. Change the entity (any property, just to make it dirty)
5. Commit the transaction

Original issue reported in Infinispan issue tracking:
https://issues.jboss.org/browse/ISPN-7595


Comments from Infinispan maintainer:
The root cause is the order in which synchronizations are invoked in Atomikos. While JBossTM (which we use for both development & testing) invokes Synchronization#beforeCompletion in the same order as they were registered (#afterCompletion is invoked in the opposite order), Atomikos holds these in a stack and #beforeCompletion is invoked in the opposite order. As Hibernate registers itself during #openSession and Infinispan during #persist, Infinispan starts committing the transaction, an then Hibernate calls flush on the dirty entity - but at this point Infinispan does not allow to modify the transaction in commit process anymore.
