Subject [jira] [Commented] (DERBY-3823) NullPointerException in stress.multi test
Date Mon, 10 Oct 2011 23:40:31 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13124579#comment-13124579
] 

Mamta A. Satoor commented on DERBY-3823:
----------------------------------------

I applied Dag's changes to trunk and saw the behavior from my test program, ie embedded gave
an error for metadata change while the resultset is still open but network server allowed
the metadata change but didn't reflect those changes in resultset's metadada descriptor.
