We need to merge the two different implementations of jca in the 3.2.x and jboss4
series.
The spec does allow a JCA1.5 implementation in a j2ee1.3 server

The key part are the changes to the transaction manager.
These need properly stress testing before they are applied to jboss-3.2.x
1) Last Resource Gambit - and associated refactoring
2) Transaction inflow - XATerminator implementation

The jdbc resource adapters are also out of synch. Bill has some modfiications
in 3.2.x that are not in jboss head.
