cluster synchronization NPE
---------------------------

                 Key: JCR-931
                 URL: https://issues.apache.org/jira/browse/JCR-931
             Project: Jackrabbit
          Issue Type: Bug
    Affects Versions: 1.3
            Reporter: Xiaohua Lu


we have a 4 machines setup and encountered the following NPE in one of the nodes. After restarting
tomcat, the problem seems to go away. But it would be nice to find out why.
