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
