Annotates a method which is invoked when the Service is being unregistered from the 
 OSGi registry.
 The method is called when the component's bundle is stopped, or when one of its
 required dependency is lost, or when a 
LifecycleController is programatically used to
 stop a service.
 
 
 
Usage Examples
 
 
 @Component
 class MyComponent implements MyService {
     @ServiceDependency
     private LogService logService; // Required dependency over the log service.
     
     @Stop
     void stop() {} // We are unregistering from the OSGi registry.     
 }
