      X x = (X) clazz.newInstance();
      Class[] argTypes = { String.class };
      Method method = clazz.getMethod("objectMethod", argTypes);
      Annotation[] annos = method.getAnnotations();
      for(Annotation anno:annos){
        System.out.println(anno);
      }
      System.out.println();
