[jira] [Comment Edited] (DERBY-6623) DatabaseMetaDataTest fails
intermittently
[ https://issues.apache.org/jira/browse/DERBY-6623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14042492#comment-14042492 ]

---------------------------------------------------------------
Attaching [^derby-6623-2], which adds an extra ordering using IndexDescriptor's toString-method. This imposes a total order on the rows returned from the metadata query, so hopefully we get rid of the Heisenbug. Note that this caused another unique constraint to be chosen in the example that failed. DababaseMetaDataTest passed. Re-running regressions.
