/** Find the nearest enclosing class with native methods. */
static Class<?> findDirectMappedClass(Class<?> cls) {
  Method[] methods = cls.getDeclaredMethods();
  for (Method m : methods) {

  }
  int idx = cls.getName().lastIndexOf("$");
  if (idx != -1) {
    String name = cls.getName().substring(0, idx);
    try {

    } catch(ClassNotFoundException e) {
      // ignored
