Michael McCandless updated LUCENE-3439:
---------------------------------------
Attachment: LUCENE-3439.patch
Patch, adding missing ensureOpens, adding volatile to IW's close/closing bools,
and fixing the scary bug where we invoke del policy (and possibly delete file)
on a closed writer.
> add checks/asserts if you search across a closed reader

>
> if you try to search across a closed reader (and/or searcher too),
> there are no checks, not even assertions statements.
> this results in crazy scary stacktraces deep inside places like FSTs/various
> term dictionary implementations etc.
> In some situations, depending on codec, you wont even get an error (i'm sure
> its fun when you try to retrieve the stored fields!)
