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

        
        for (int i = 0; i < numRings; i++) {
          Coordinate[] interior=decimate(line.getInteriorRingN(i)).getCoordinates();
          forceClosed(interior);
