------------------------------------
Summary: GeoPath behavior with indentical 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
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.
