RegistryShutdownListener抛出异常

根据service lifecycle上的文档我应该能够实现RegistryShutdownListener并整理我的资源（在这种情况下，关闭一个线程池），但是它抛出一个异常，似乎试图重新初始化我的服务为了执行关机监听器！？RegistryShutdownListener抛出异常

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服务registryDidShutdown()但执行人ISN” t a aivemind service AFAIK，它的一部分java.util.concurrent

找到后ing this我可以看到这是一个错误。解决办法是使用服务的接口（有时我会跳过），而不是在hivemodule中使用构造和接口的实现。
