I don't see your point. What is missing in Java's interfaces.
If it's that you don't have to touch existing code (as F.H. wrote)
that has to do with supertyping, not with the abstract classes concept
of Sather (Or am I completetly wrong here?).
Can you give an example of what you mean and what you think
is wrong about Java's interfaces?
