AFAIK, application has always assume the responsibility of closing
IndexReader instances.
However, with 2.9, this is the first time, IndexReader can be
instantiated via a getter from IndexWriter.
Previously, IndexReaders are usually constructed via
IndexReader.open factory method. Having a getter on an IndexWriter
makes it unclear from the API point of view.
IndexReader instances are encapsulated inside IndexWriters, and
IndexWriters sort of own the IndexReaders, which can be a good
thing: IndexWriter may want to pool these IndexReader instances etc.
Of course, this is nothing some simple JavaDoc can't fix :)

Thanks Mark for the pointer, I thought somehow that lucene closed
them as a convenience, I don't know if it did that in previous
releases (aka 2.4.1) but I'll close them myself from now on.

Standard convention is that you close our own readers, not the methods
you pass them into.

I'm trying to track a bug in my application using Lucene rc5, its
regarding Readers. I've noticed that when I index, not every reader
gets closed, so I eventually run out of avail. fd's.
Before trying to reproduce this problem using the smallest code
possible, I'd like to know if lucene is supposed to close every reader
in a Document after the IndexWriter.updateDocument(Term, Document) has
been called?
Is there a path where lucene may "wait" before closing the readers?
Maybe after it indexes some other documents?
In my case, I am using one Reader in my field and it is a
BufferedReader(), but I don't think that should make any difference
(I'll re-try with a standard reader).
Can someone confirm that after an updateDocument all readers in the
document should be closed by lucene?
