Hi !
I just upgraded from Lucene 2.3.2 to Lucene 2.4.0.
I've been using IndexReader.reopen() with 2.3.2 just fine for a long
time now.
With 2.4.0, reopening the same index (hence, a 2.3.2 index), I'm
getting spurious AlreadyClosedExceptions thrown from inside reopen():
"trace": "org.apache.lucene.store.AlreadyClosedException: this

This looks like it could be LUCENE-1453 (fixed on trunk). Does this
exception happen on trunk Lucene? Are you opening the original reader
w/ String or File path?
Is the javadoc about this method still correct ? That is, do I need
to close
the old reader instance manually after reopen() returned a new
instance as
is stated there ?
This is what I was doing in 2.3.2 (and am still doing in 2.4.0).
Yes, you have to close the old reader.
If I remove the close() call I don't get the error anymore but won't
that leak ? Or is the javadoc for IndexReader.reopen() just wrong ?
Andi..
ps: that javadoc uses a variable called 'new'. Isn't that a java
keyword ?

Good point! It is not valid java code (in the javadocs). I'll fix!
