determining the occurrence of a second class and further determining whether the second class includes an instance of the Method of the first class;

determining whether the instance of the Method in the second class overrides the Method of the first class;

altering the compiled code of the Method of the first class in response to the further determining whether the instance of the Method in the second class overrides the Method of the first class; and

operating the computer system in accordance with the altered compiled code.

2. A method as claimed in claim 1 , further comprising marking the Method of the first class as final.

3. A method as claimed in claim 1 , further comprising determining whether the Method of the first class is final before altering the compiled code.
