Subject Re: Type Safety in StateMachineProxyFactory
Date Sat, 01 Dec 2007 19:26:12 GMT
The changes look good.

I had been wondering how to do a type safe proxy factory method ever
since generics were introduced, but I didn't ever realize how until I
stumbled across some code at java.net a few months ago.  I comes in
handy anytime I build or use a proxy.
