Subject [jira] [Commented] (DERBY-6306) XplainStatisticsTest.testSimpleQuery: BEGIN_COMP_TIME unexpectedly NULL
Date Wed, 28 Aug 2013 10:29:52 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13752273#comment-13752273
] 

Knut Anders Hatlen commented on DERBY-6306:
-------------------------------------------

Thanks, Rick and Bryan, for your comments. I agree that it makes sense to treat this as a
test bug in this issue, and open a new issue if we think the actual statistics should be changed.
Feel free to open such an issue if you'd like.
