I see I have done my job correctly :)

You're not never supposed to be able to have access to a 
GBeanMBeanAttribute instance directly.  It is an abstraction internal 
to the GBeanMBean implementation.  The only way to perform an 
integration test should be through the public interface on GBeanMBean.
