Re: [Hibernate] Ohhh this looks cool

I'm currently re-implementing the Proxy feature using CGLIB, as an
alternative
to JDK proxies. Its turning out really nicely. I have always been so
frustrated
by the inability to intercept calls to an object if the object doesn't
implement
an interface. CGLIB seems to solve that problem nicely.
