Jackrabbit fails for "unexpected error while syncing of journal" and stops responding
-------------------------------------------------------------------------------------

                 Key: JCR-2126
                 URL: https://issues.apache.org/jira/browse/JCR-2126
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: clustering
    Affects Versions: 1.3
         Environment: Webspshere, AIX server, Clustered environment.
            Reporter: Badal


In a clustered environment, Jackrabbit stops processing any request on receiving this exception
"unexpected error while syncing of journal:null"

This happens inconsistently and now sure about the root cause of this issue. Jackrabbit should
gracefully handle this exception and should not stop responding.

Exception stack trace:
[ClusterNode-596d] Unexpected error while syncing of journal: null
java.lang.NullPointerException
