Xid recovery scans assume same list ordering

                 Key: JBTM-823
                 URL: https://issues.jboss.org/browse/JBTM-823
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Recovery
    Affects Versions: 4.14.0, 4.6.1.CP08
            Reporter: Jonathan Halliday
            Assignee: Jonathan Halliday
             Fix For: 4.15.0, 4.6.1.CP09

For RM driven recovery, two consecutive recovery scans are performed with a delay between. Only Xids appearing in both are eligible for recovery. This prevents momentarily prepared, normally executing branches from being incorrectly aborted.

RecoveryXids.toRecover incorrectly compares the content of the two lists, leading to some Xids not being recovered in a timely manner if the list content or order partially changes between scans.
