Subject [jira] [Commented] (DERBY-3823) NullPointerException in stress.multi test
Date Tue, 07 Feb 2012 18:50:59 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13202620#comment-13202620
] 

Mike Matrigali commented on DERBY-3823:
---------------------------------------

I am wondering if the consensus is still that we should not backport this fix to 10.8?  It
has run successfully for some time now in trunk.  The fix looks localized to me.  I understand
that it does not fix everything, but seems to be better than no fix.  What is the risk of
the fix?

For some reason we seem to be seeing the stressmulti error quite a lot in 10.8 nightly runs,
tracked under 
DERBY-5435
