Final nestmates spec

Hi Dan,

I have one query with regards to the processing of the NestMembers 
attribute. Originally when I wrote the draft I copied the InnerClasses 
text and that included prohibiting duplicate entries in NestMembers. You 
dropped that restriction from the spec (though I haven't yet removed it 
from the VM). How does that interact with the Class.getNestMembers() 
API? Should it return the raw NestMembers contents (which may include 
duplicates - including additional references to "self") or should it 
return the set of members (ie no duplicates, including self)?
