Hi, Why is almost everything in the API final? OK, I understand there is a security problem and not making things final could potential open security holes. What I'm puzzled about is that the rest of the JDK doesn't use this pattern and so I wonder if it is still effective this way? I'm asking this because the penalties are significant, since you can not easily extend the API because you can't subclass most framework classes.
