org.hotswap.agent.javassist.CtClass
An instance of CtClass represents a class. It is obtained from ClassPool. @see ClassPool#get(String)

    public void swapClasses(Class original, String swap) throws Exception {
        // need to recreate classpool on each swap to avoid stale class definition
        ClassPool classPool = new ClassPool();
        classPool.appendClassPath(new LoaderClassPath(original.getClassLoader()));


        CtClass ctClass = classPool.getAndRename(swap, original.getName());


        reload(original.getName(), ctClass.toBytecode());
    }
