Indeedy - JMock can mock interfaces, not actual classes, which is a  
bit of a pain until/unless you're willing to do a bit of refactoring  
to accomodate. In this case, you'd have to design some kind of facade  
IMaxObject interface (say), and then program against that (and then  
link it into the real MaxObject somehow, perhaps via another concrete  
subclass of MaxObject which implements IMaxObject).

Yes, it's a hassle; probably not worth it for a one-off (old-skool  
stubs are easier), but perhaps worth thinking about for some big- 
project agile/extreme goodness.
