Hiram is the one who did the transaction parts of the MDB, but I would
geuss this is what is going on: An MDB is ALWAYS transacted (the receipt
that is), the flags only determins under what TX context the bean is
invoked. This mean there will allways be a transaction going on under
the hood.

That was fixed in JBossMQ during the time I implemented the Dead Letter
Queue handler, which was commited after the RH stuff. There is a change
note about it.
