We recently upgrade our lucene library from 1.9.1 to 3.6.1 and we run into
multiple AlreadyClosedException when doing search. Here is the stack:

On the source code side, we open and did the search like this:
reader = IndexReader.open(FSDirectory.open(newFile(request.indexPath)));
searcher = new IndexSearcher( reader );
searcher.search( query, filter, collector );
I do not see any reason why this could happen. The IndexReader is not being
shared with other thread.
