Get classname from ClassDelegateActivityBehavior

For validation purposes, we are checking the delegate classes of service tasks in parse listeners.

It seems like it is not possible to extract the delegate classname of ClassDelegateActivityBehavior instances. However, this is possible for ClassDelegateExecutionListeners, which provide getter methods for the classname via the ClassDelegate superclass.

It would be great if the delegate classname in delegate behaviors could be extracted like this too. Or is there another way to do this?
