Subject [jira] Commented: (LUCENE-2307) Spurious exception in TestIndexWriter
Date Thu, 11 Mar 2010 10:40:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12844004#action_12844004
] 

Michael McCandless commented on LUCENE-2307:
--------------------------------------------

This is odd -- that test calls close(true) on IW, meaning wait for all merges to complete.
 So offhand I don't know why a merge is being aborted... that should only happen if close(false)
is called.  Strange....
