If you want to make the method available to other random code, then yes, you have to override it to make it a public method, as in your first example.
Ok, I'll live by that rule now. But I don't really understand the reasoning behind it.
Consider Object. It's clone() is protected. Now it is not available to any class in the Java World unless it redefines this method. While I don't know what's the spirit behind such an implementation, it definitely is not making use of code reuse, you see.
