 * The JTA {@link javax.transaction.Synchronization} Hibernate registers when needed for JTA callbacks.
 * <p/>
 * Note that we split the notion of the registered Synchronization and the processing of the Synchronization callbacks
 * mainly to account for "separation of concerns", but also so that the transaction engine does not have to hold
 * reference to the actual Synchronization that gets registered with the JTA system.
