I'm using ClassFile.renameClass as in jbossretro in order to replace instances of a class in a jar to my own class.
This is what I wants to achieve:
Some classes are using class A:
public class A {
I've created a new class AA:
public class AA extends A{
....(overwrite some methods)

I want to replace the A instances with AA in the jar.
In the jar I have class B as follows:

public class B {
private final A a = ....;
I cannot replace the final fields. 
I've looked at JBosRetro - when replacing the StringBuilder with JBossStringBuilder - they have the same bug. final field referring to StringBuilder are not replaceable. Is there a way to replace the final declaration - I'm working on the bytecode.
