Subject [jira] [Commented] (DERBY-5554) NullPointerException in generated VTI code
Date Thu, 21 Jun 2012 18:57:42 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13398744#comment-13398744
] 

Rick Hillegas commented on DERBY-5554:
--------------------------------------

Ported 1351714 and 1351795 from trunk to the 10.9 branch at subversion revision 1352648.

Ported 1351714 and 1351795 from trunk to the 10.8 branch at subversion revision 1352652.

The port to 10.8 involved a change to SysDiagVTIMappingTest to account for a catalog query
which returns different results in 10.8. That is because the SYSUSERS table does not exist
in 10.8.
