Subject [jira] Commented: (LUCENE-415) Merge error during add to index (IndexOutOfBoundsException)
Date Thu, 18 May 2006 20:34:06 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-415?page=comments#action_12412415 ] 

Yonik Seeley commented on LUCENE-415:
-------------------------------------

Andy, how easy is it for you to replicate the problems that getChannel() solved?  Is it possible
to check if the addition of setLength() alone solves the problem.  getChannel() really shouldn't
be needed.

(note: the close() on the fileChannel in my version isn't right since it will cause everything
to be closed.)
