Subject [jira] Resolved: (DERBY-4721) NullPointerException on StressMultiTest in language layer
Date Thu, 05 Aug 2010 22:15:17 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4721?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Myrna van Lunteren resolved DERBY-4721.
---------------------------------------

    Bug behavior facts: [Regression, Regression Test Failure]  (was: [Regression])
            Resolution: Cannot Reproduce

Since the fix for DERBY-4279 was backed out, I haven't seen this again, so I'm resolving this
as 'could not reproduce'. If anyone has another suggestion on how to handle this issue, feel
free to chance status.

> Saw NPE for testStressMulti on trunk(10.7 revision 956758) on a windows machine with
ibm15. May be related to commit made for DERBY-4279,  since it seems to have caused some other
NPEs in StressMultiTest in the Tinderbox too.
