The message warns you that if your transaction fails your data may be left
in an inconsistent state.  You have more than one participant in a jta
transaction, but one of them only supports local transactions without two
phase commit.

The warning might be excessive at this point since in order to recover from
such failures you would need to run tyrex as your tm and use a jms provider
that supported recovery which I believe jbossmq does not.
