Updated Gist after I got the contraction hierarchies working

gistfile1.java

public class TestGH {

  @Test
	public void test() {
		GraphHopper gh = new GraphHopper().forServer().contractionHierarchies(true);
		gh.load("./london.osm");
		GHRequest request = new GHRequest(51.559997,-0.226593,
				51.448016,0.063171);
		request.algorithm("dijkstrabi");
		StopWatch sw = new StopWatch().start();
		GHResponse response = gh.route(request);
		System.out.println("Route Time: " + sw.stop().getSeconds());
		System.out.println(response.distance() + " " + response.time());
		PointList points = response.points();
		for (int i = 0; i < points.size(); i++) {
			System.out.println(points.latitude(i) + " : " + points.longitude(i));
		}
	}

}
