XAResource recovery - empty scan result correlation is broken

                 Key: JBTM-827
                 URL: https://issues.jboss.org/browse/JBTM-827
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Recovery
    Affects Versions: 4.6.1.CP11, 4.14.0
            Reporter: Jonathan Halliday
            Assignee: Jonathan Halliday
             Fix For: 4.15.0, 4.6.1.CP12

Per JBTM-602, we need to correlate recovery scan results for the same RM even when these are obtained using different XAResource/Connection instances. The current algorithm for this walks the old scans and replaces the stale XAResource with the newer one where Xids from the two scans match. However, this is insufficient as one or both passes may have resulted in an empty set of Xids. Update matching to fallback to using isSameRM when Xid matching is not possible, in order to increase robustness where one or both scans have empty results.
