I can't see how that makes sense, even with the above (un-idiomatic?)  
idea. The compiler should not emit references to *abstract* methods.

I think this looks like a case of class attributes not affecting methods:  
"Address" is declared as an abstract class, but the compiler doesn't  
realize that its methods are abstract too. They are simply declared as  
method declarations without a body.

This is similar to another old bug (now fixed, I believe), when methods of  
"final" classes were still implicitly virtual.
