Michael McCandless commented on LUCENE-7102:
--------------------------------------------

+1, nice catch.

I'm not sure we should even allow "sort missing first"...

> LatLonPoint newDistanceSort fails with "sort missing first"

> The distance sort comparator creates bounding boxes when the priority queue 
> is full, to speed up sorting.
> But with missing values (which we don't test), they can be e.g. -Inf/+Inf and 
> we do the wrong thing (e.g. try to make illegal infinite bounding boxes).
