I have a J2EE application. It starts a transacition and involve two XA resource. One is JBoss messaging while the other is Oracle database.
I set a debug breakpoint in the XAResource.commit API of the two XA resources.
During the transaction commit phase, I only let one XA resource commit and before the other XA resource commit, I kill the JBOSS application server.
After JBoss restart, I can see following warning log continually poll out. Transaction manager has two transaction branches record in the state but only one transaction branch fails to commit. The failed branch can never get to be recovered any more.
I think this should be a regression, as the same case can work for JBoss TS 4.2.3 - SP6.
