public interface TransactionSynchronizationRegistryLookup
If we are in a JTA transaction that tx.commit has already been called and
we are invoked as part of a interposed synchronization, we need to use the TransactionSynchronizationRegistry
to register any further needed synchronizations. This interface is how we will lookup the
TransactionSynchronizationRegistry. Although, in most cases, we will already have it
injected via some other means (avoiding a JNDI lookup).
See ISPN-1168 for more details.
