Subject [jira] [Closed] (AMQ-4546) kahadbstore nullpointerexception after restart
Date Thu, 15 Aug 2013 21:40:30 GMT

     [ https://issues.apache.org/jira/browse/AMQ-4546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Timothy Bish closed AMQ-4546.
-----------------------------

    Resolution: Cannot Reproduce

No test case here to validate.  There are a bunch of fixes in the 5.9-SNAPSHOT so I would
suggest testing against that and if you can reproduce then please reopen and attach a test
case.
