Karl Wright commented on LUCENE-6597:
-------------------------------------
Also, David, this particular patch is *not* rocket science IMHO. It just
corrects a case I broke with WGS84, which a test suite a work caught. If you
want to *extend* the functionality, really we should be talking about another
ticket.

> The following GeoCircle construction:
> {code}
> new GeoCircle(PlanetModel.SPHERE, -20.0 * RADIANS_PER_DEGREE, -20.0 *
> RADIANS_PER_DEGREE, Math.PI);
> {code}
> ... fails as follows:
> {code}
> Degenerate/parallel vector constructed
> {code}
> The reason is that the plane normal vector cannot be computed in that case.
> A special case is warranted for circles that cover the whole globe.
