4.ArjunaJTS/jtax
com.arjuna.ats.internal.jta.transaction.jts.subordinate.jca.coordinator.ServerTransaction Line 108
Possible null pointer dereference of ServerTransaction._theXid in com.arjuna.ats.internal.jta.transaction.jts.subordinate.jca.coordinator.ServerTransaction.save_state(OutputObjectState, int)

As mark says, state machine should have stopped that scenario but it looked like it was worth a quick fix in case the class is used in an as yet untested code path
