Michael McCandless reopened LUCENE-1453:
----------------------------------------
I'm seeing a failure in back-compat tests ("and test-tag
-Dtestcase=TestIndexReader"):
{code}
[junit] Testcase:
testFalseDirectoryAlreadyClosed(org.apache.lucene.index.TestIndexReader): FAILED
[junit] did not hit expected exception
[junit] junit.framework.AssertionFailedError: did not hit expected exception
[junit] at
org.apache.lucene.index.TestIndexReader.testFalseDirectoryAlreadyClosed(TestIndexReader.java:1514)
{code}
(I assume, but I'm not certain, it's from this fix...).
> When reopen returns a new IndexReader, both IndexReaders may now control the
> lifecycle of the underlying Directory which is managed by reference counting

> Rough summary. Basically, FSDirectory tracks references to FSDirectory and
> when IndexReader.reopen shares a Directory with a created IndexReader and
> closeDirectory is true, FSDirectory's ref management will see two decrements
> for one increment. You can end up getting an AlreadyClosed exception on the
> Directory when the IndexReader is open.
> I have a test I'll put up. A solution seems fairly straightforward (at least
> in what needs to be accomplished).
