> Currently, the tessellation in some situations when it has not successfully
> process all points in the polygon, it will still return an incomplete/wrong
> tessellation.
> For example the following code:
> {code:java}
> public void testInvalidPolygon() throws Exception {
> String wkt = "POLYGON((0 0, 1 1, 0 1, 1 0, 0 0))";
> Polygon polygon = (Polygon)SimpleWKTShapeParser.parse(wkt);
> expectThrows( IllegalArgumentException.class, () ->
> {Tessellator.tessellate(polygon); });
> }{code}
> will fail as the tessellator return a wrong tessellation containing one
> triangle.
