Michael McCandless commented on LUCENE-3851:
--------------------------------------------
I committed a fix; it was a test bug: when the number of indexed terms was 0
mod termIndexInterval... the test incorrectly thought the last term would be an
indexed term.
I also added some missing asserts so the next time this happens the exceptions
won't look so scary :)
