Jason Rutherglen commented on LUCENE-1314:
------------------------------------------
That worked Erik.
I executed TestIndexReaderReopen using the LUCENE-1314 patch 8 times via
command line and did not see the error.
Then tried TestIndexReaderReopen in trunk and saw this the first time:

> Based on discussion
> http://www.nabble.com/IndexReader.reopen-issue-td18070256.html. The problem
> is reopen returns the same reader if there are no changes, so if docs are
> deleted from the new reader, they are also reflected in the previous reader
> which is not always desired behavior.
