Hi Chris,

I think the part that checks that a final field is not set more than 
once is still useful (to catch conflicts betwen defaultReadObject() and 
explicitly setting the field). And if we keep that, there's no overhead 
in keeping the FieldAccessContext.checkAllFinalsSet() method and just 
propagating it to FieldAccess (FieldUpdater) API and removing it's call 
from ObjectInputStream code. So we don't impose this on the user, but 
give him an option.

Regards, Peter
