Jason Rutherglen updated LUCENE-1314:
-------------------------------------

    Attachment: LUCENE-1314.patch

Related to LUCENE-1516 I'm seeing a bug.

The test case in TestIndexReaderClone.testLucene1516Bug recreates the
bug. Basically a reader is created, incRefed, a clone is made, the
reader is decRefed, then incRefed again where the
reader.deletedDocsRef assert > 0 fails.

> 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.
