> The problem:
> If you invoke an equals(Object o) method on a proxy, then the proxy might directly access private fields if o is of the same type as the proxied object itself.
> But if the proxy directly accesses private fields, then no interception occurs and the equals method will effectively only get the empty values from proxy itself (which enhances o's class and thus has the exact same fields).
> The solution:
> We need to 'unpack' the proxy parameter and instead provide the underlying contextual instance
> if (inteceptedMethod.equals("equals") && param.intanceOf(bean.getType()) && isOurProxy(parram)
> {
>   unpackedParam = getUnderlyingContextualInstance((NormalScopedBeanInterceptor) param);
>   invoke("equals", unpackedParam);
> }
