> If we marshal an object graph containing N distinct objects that are all 
> equal, then after unmarshalling we must get N distinct objects and not N 
> references all pointing to just 1 object. It's easy to miss this requirement 
> for primitive wrapper types (like Integer).
> Also, when we marshal a graph containing N references to the same object, 
> after the unmarshalling this property must be maintained.
