There is no changes in that area that would change the semantics of the
XA/JCA implementation.

Also I have to take back my statement that there is a case when driver will
not work as expected. JTA does not specify anything in regard to loosely or
tightly coupled threads. Your implementation is a loosely-coupled thread
implementation and is, to my understanding, perfectly XA compliant.
