从Controller Method调用另一个Controller方法

Question

我在控制器中有方法。我想从第一个方法调用同一个控制器中的另一个方法（两个都是RestAPI）但是它会生成

public Result make_something_easy(Long Id){
  // Some easy code

  Thread hard_independent_thread = new Thread() {
      @Override
      public void run() {
           make_something_hard(object.id);
           // no result required - just do that like void method 

      }
   };

   hard_independent_thread.start();

   return ok(Json.toJson(object));
}


// You can call this on API separately
public Result make_something_hard(Long Id){
   // Some code
   // 30 second and more... 
   return ok();
}

但代码 make_something_hard(object.id);

发生此错误。我不知道为什么：
