    Description

      I found another regression (besides JBEAP-6326) for behavior of CMR datasource which came with DR6 (Narayana 5.3.5.Final) and is regression against DR5 (5.3.3.Final)

      The scenario which I run is following

      • enlist test xa resource
      • enlist cmr db resource
      • prepare cmr db resource
      • prepare test xa resource
      • commit cmr db resource
      • crash app server
      • start server and halt connection to DB
      • do recovery of test xa resource which is expected being committed

      What happens is that the second resource (test XA resource) is not committed but is rolled-back. By my investigation I think that the regression came from changes under com.arjuna.ats.internal.jta.recovery.arjunacore#getNewXAResource(Xid xid) (but it's only observation and it could be wrong interpretation).
      In log the rollback could be seen being caused by JTANodeNameXAResourceOrphanFilter which votes for rollback.
