It's not specified, Proxy pre-dates hidden classes although its Proxy did require some changes to specify that it can't be a proxy to a hidden class. Given the getProxyClass is deprecated then it may be better to have it work the same way as it has always done.

If Proxy::newInstanceClass is changed to return an instance of a hidden class then spec changes are needed. Maybe too early to think about that now as there is a lot of analysis work required to do before going near code.
