code: private static String targetToString(Object target) {
  		if (target instanceof Class) {
  			return ((Class<?>) target).getName();
  		} else {
  			return target.toString();
  		}
  	}

  <p>For example, returns
  "io.netty.example.http.router.HttpRouterServerHandler" instead of
  "class io.netty.example.http.router.HttpRouterServerHandler"
