Can JSF2 application be deployed in websphere 7 ?

Websphere 7 has support only to JSF 1.2

But if we use a separate classloader for our webapp loads JSF2 api  will the aaplication work ?

I deployed an application with richfaces 4 milestone 5 build.

When I hit the url , it loads the welcome page ( login ) and I get the stack over flow exception as given below

Any clues ?
