> {code}
> (.*\.|^)class\..*
> {code}
> should be 
> {code}
> (.*\.|^)class(\.|\[).*,.*\['class'\](\.|\[).*,.*\["class"\](\.|\[).*
> {code}
> it will block such as
> {code}class['classLoader']  , model['class'].classLoader , model["class"].classLoader
{code}
> I think use regex to block parameterName is not best solution,It must be done in ValueStack,
seperate entry point , one for serverside, one for client side,client side should add more
restriction and security checks.
