Subject [jira] Commented: (LUCENE-1992) intermittent failure in TestIndexWriter. testExceptionDuringSync
Date Mon, 19 Oct 2009 09:26:31 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12767258#action_12767258
] 

Michael McCandless commented on LUCENE-1992:
--------------------------------------------

bq. Should this also applied to bw branch (2.4 for) 2.9 and (2.9 for) 3.0? 

No, it can only be applied on trunk.

That call tells ConcurrentMergeScheduler to expect exceptions during this test, which when
autoCommit is true (which this test is doing everywhere except trunk) will happen because
when a merge completes, it'll commit and call Directory.sync which throws the intentional
exception.
