why your proxy class does not have at least a format, methodDict and superclass?
In the past
Behavior new something was carashing the vm because methodDict was nil and boum it crashed.
I fixed that long time ago.
Now I think that a class proxy cannot be just the same as an object proxy from the vm look at structure.
