annotations on event set methods that interact with interceptors can result in 
compilation errors

         Key: BEEHIVE-1079
         URL: http://issues.apache.org/jira/browse/BEEHIVE-1079
     Project: Beehive
        Type: Bug
  Components: Controls  
 Environment: xp
    Reporter: matt c


An event set within a control interface with annotated methods can result in 
compilation errors.  The errors will only occur when the interface has no 
methods of its own (annotated or not).

Repro:
Easy, just create a control interface with an event set that has annotated 
methods that interact with interceptors and compile (if you add any method to 
the interface you will not see the error).  Ex:

@ControlExtension
public interface CallbackOnlyControl extends ExtensibleControl 

    @EventSet
    public interface CallbackHere extends MessageBufferFailure {      

        @MessageBuffer(retryCount=2, retryDelay="1s")
        void bufferedCallback();     

    } 
}

Error:
