Attached a patch with the logic for filtering points.
> GeoPath behavior with identical points
> --------------------------------------
>
> Key: LUCENE-8236
> URL: https://issues.apache.org/jira/browse/LUCENE-8236
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/spatial3d
> Reporter: Ignacio Vera
> Priority: Minor

> GeoPath has the current behavior:
> * When provided a path with two consecutive identical points: In all cases it generates an {{IllegalArgumentException}} because it tries to build a plane with those two points.
> * When provided a path with two consecutive numerical identical points: In case of {{GeoStandardPath}} it throws an {{IllegalArgumentException}} because the path is too short. The case of {{GeoDegeneratePath}} is more complicated as it builds the path but the plane can be bogus. In some cases points on the other side of the world can be "In Set".
> I think the factory should filter out these points, in the same way it is done for {{GeoPolygon}}. If this is not the desired behavior then the factory should throw a consistent {{IllegalArgumentException}} in all cases.
