                 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1722
             Project: JBoss Messaging
          Issue Type: Bug
    Affects Versions: 1.4.4.GA, 1.4.0.SP3.CP08
            Reporter: Howard Gao
            Assignee: Howard Gao
             Fix For: 1.4.0.SP3.CP09, 1.4.5.GA


On node failover, clustered queue on the failed node will be merged into the queue on the back up node. If the local queue is in paging state but the failed queue has no messages to merge in, it will reset the firstPagingOrder and nextPagingOrder and therefore change the paging state to false. That makes the paging broken.

This issue were found during investigating the associated ticket.
