[Hibernate] JTATransaction + JCS read-write cache

[Gavin K. <ga...@ap...>]

I've added the TransactionManagerLookup hierarchy (which I bit from OJB
code). It's now safe to use the JCS read-write cache with JTATransaction in
any of the three supported application servers. You need to specify

hibernate.transaction.manager_lookup_class=JBossTransactionManagerLookup

for example.

Would people please test this stuff out and check that we get the
afterCompletion() callback as expected. (Enable trace-level logging.)

TIA
