---------------------------------
       Resolution: Fixed

                   Trunk

For now the check is implemented via Terms.getPayloads() until LUCENE-6390 is fixed.

> After the big spans overhaul in LUCENE-6308, we can speed up SpanNearQuery a little more:
> * SpanNearQuery defaults to collectPayloads=true, but this requires a slower implementation,
for an uncommon case. Use the faster no-payloads impl if the field doesn't actually have any
payloads.
> * Use a simple array of Spans rather than List in NearSpans classes. This is iterated
over often in the logic.
