> Text objects should not access other Text objects private members directly. 
> Both set(Text) and compareTo(Object) do.
> Because these two methods access private members of the other object, Text is 
> not subclassable. Either these two methods should be modified to use the 
> accessors that are already available, or Text should be declared as a final 
> class, because as it exists today it is not subclassable.
