Is geometryA.intersections(geometryB) the same like geometryB.intersections(geometryA)?

Question

I have two geometries(polygons) and use the intersection function of the geometries to get the intersection geometry with geotools.

The result surprised me - why:

• polygonA.intersection(polygonB) - throw an exception
• polygonB.intersection(polygonA) - get an valid geometry

When I do the same with PostGis, I get in both cases a valid geometry: It should be no difference between polygonA.intersection(polygonB) or polygonB.intersection(polygonA). The result should be the same.

I use geotools in Version 31.0. It that a bug or understand the method intersection not correct.
