Subject [jira] [Commented] (DERBY-3823) NullPointerException in stress.multi test
Date Sun, 09 Oct 2011 02:35:29 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123599#comment-13123599

Dag H. Wanvik commented on DERBY-3823:
--------------------------------------

Thanks, Mamta. I agree with you opinion concerning 10.8. Your understanding of my patch is
sorrect. As for the correctness of the resultset description my concern was slightly different:
I was wondering if the retrieved result set description actually still describes the result
set (for which we are retrieving the metadata), if the ps has been invalidated and recompiled
(presumably after the result set was generated).
