    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=36889#action_36889 ] 

Gail Badner commented on HHH-5173:
----------------------------------

Thanks for the test case!

I tested using your patch on MySQL and the test passed.

If I understand correctly, this is a bug in hsqldb, not hibernate.

Please confirm.

Thanks,
Gail
