RegistryShutdownListener拋出異常

根據service lifecycle上的文檔我應該能夠實現RegistryShutdownListener並整理我的資源（在這種情況下，關閉一個線程池），但是它拋出一個異常，似乎試圖重新初始化我的服務爲了執行關機監聽器！？RegistryShutdownListener拋出異常

Hivemodule.xml：

<service-point id="MyService" interface="package.MyService"> 
    <invoke-factory><construct class="package.MyService" /></invoke-factory> 
</service-point>

package.MyService.java：

public class MyService implements RegistryShutdownListener 
{ 
... 
    private ExecutorService executors; 

    private void intitialise() 
    { 
... 
    executors = Executors.newFixedThreadPool(3); 
... 
    } 

... 

    @Override 
    public void registryDidShutdown() 
    { 
     if (executors.isShutdown()) 
      return; 
     executors.shutdown(); 
    } 
}

附言：我明白，你不能引用到其他的HiveMind服務registryDidShutdown()但執行人ISN」 t a aivemind service AFAIK，它的一部分java.util.concurrent

找到後ing this我可以看到這是一個錯誤。解決辦法是使用服務的接口（有時我會跳過），而不是在hivemodule中使用構造和接口的實現。
