IIRC, you will get a different Package for each class loader, for a 
given package name. Certainly classes with the same package name will 
not have Java access to default/protected 
members/classes/interface/constructors from different class loaders.

But yes, a list of classes is not necessarily complete. Also, IIRC, 
Proxy dynamically inserts classes into packages as well.
