Subject [jira] Commented: (LUCENE-2618) Intermittent failure in 3.x's backwards TestThreadedOptimize
Date Fri, 22 Oct 2010 19:38:17 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12923987#action_12923987
] 

Michael McCandless commented on LUCENE-2618:
--------------------------------------------

OK so I think we should fix this test to also accept an IndexTooOldExc during close.

The .optimize() call for only the 29.nocfs case (for some reason) enrolls 2 pending merges
to IW.

The 1st merge hits an exception, throwing up through the .optimize() to the test.  But the
2nd merge remains queued, and in IW.close() we give MS a chance to run any merges it needs
to, and that 2nd merge then also hits an exc.
