> 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.
