FileNotFoundException triggered by maybeeMergeSergments
-------------------------------------------------------
Key: LUCENE-576
URL: http://issues.apache.org/jira/browse/LUCENE-576
Project: Lucene - Java
Type: Bug
Components: Index
Versions: 1.9
Environment: 1.9.1, OSX, JDK 1.4.2
Reporter: Ian Boston
IndexWriter.magbeMergeSergments appears to be attempting to merge the same
segments twice in a row which causes a FileNotFoundException in the fnm file
for the segment deep inside FiledInfos.<init>
In the IndexWriter.maybeMergeSegments below, minSegement has the same value on
2 consecutive loops, the InfoStream output looks like

I will put some more debug in maybeMergeSegments to see if I can find out why
(unless someone already knows the answer :) )
Thanks
