Subject [jira] Commented: (DERBY-4071) AssertFailure when selecting rows from a table with CHARACTER and VARCHAR columns
Date Tue, 10 Mar 2009 14:36:51 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12680475#action_12680475

Kristian Waagan commented on DERBY-4071:

Normally the developer resolves the issue when he/she, or the community, feels that the issue
has been properly addressed.
Then the reporter should verify the fix and close the issue if the problem is no longer seen.
This isn't a strict process, but what happens most of the time.

As far as I understand, you have already verified that the patch fixes the problem you experienced,
but I'm not sure if Dag is done working on this issue yet. The code hasn't been committed
to neither the trunk nor the 10.4 branch.
My opinion is that it is a little early to declare victory, but your feedback on the patch
is very welcome and may speed up the process :)

Thank you for taking the time to report bugs and testing out patches!
