com.vividsolutions.jts.geom.GeometryFactory.createLinearRing()
Creates a LinearRing using the given Coordinates; a null or empty array will create an empty LinearRing. The points must form a closed and simple linestring. Consecutive points must not be equal. @param coordinates an array without null elements, or an empty array, or null

        // holes that touch at multiple points (and, weirdly, does not have a method
        // to detect this other than this crazy DE-9IM stuff


        List<Polygon> polygonHoles = new ArrayList<Polygon>();
        for (Ring ring : holes) {
            LinearRing linearRing = factory.createLinearRing(toCoordinates(ring.geometry));
            Polygon polygon = factory.createPolygon(linearRing, new LinearRing[0]);
            for (Iterator<Polygon> it = polygonHoles.iterator(); it.hasNext();) {
                Polygon otherHole = it.next();
                if (otherHole.relate(polygon, "F***1****")) {
                    polygon = (Polygon) polygon.union(otherHole);
