Right, I am seeing the problem now with JBoss JTA 4.9.0.  Clearly 4.6.1 swallowed some stuff, as did the DummyTM.  

Reopening the JIRA, will look into this today/tomorrow.

A log line is generated but that’s it.  I’m not sure how to view a log in your tests but I couldn’t see the message anywhere in the reports.

I can now reproduce “success” by using the DumyTransactionManager but I don’t think the DummyTransactionManager is handling this properly or making it apparent.
