> In SpanNotQuery, there is an acceptance condition:
> {code:java}
> if (candidate.endPosition() + post <= excludeSpans.startPosition()) {
> return AcceptStatus.YES;
> }
> {code}
> This overflows in case `candidate.endPosition() + post > Integer.MAX_VALUE`.
> I have a fix for this which I am working on. Basically I am flipping the add
> to a subtract.
