[jira] Issue Comment Edited: (LUCENE-1453) When reopen returns a
new IndexReader, both IndexReaders may now control the lifecycle of the
underlying Directory which is managed by reference counting
[ https://issues.apache.org/jira/browse/LUCENE-1453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714821#action_12714821 ]

-----------------------------------------------------------------
It was too late in the night yesterday: I think this is not really related to LUCENE-1658, but this case showed possibly a problem in my code.
As this issue is only interesting for IndexReaders opened without "Directory" but witch FS path, it was a problem with incomplete removal of the reference counting of FSDirs in an early test.
If the problem occurs again, I will reopen this issue.

> 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).
