> While this is not the default access scenario performed by Lucene it's possible in some branches to flush the segment and be able to read it before the close.
> I could reproduce the following stacktrace in high load / huge sized index but not in a unit test; disabling the batching started between .flush() and .close() seems to resolve the issue; also this batch seems totally useless as I couldn't find any chance in performance when disabling it.
