BTW, in the case that the target class implements Serializable, it is
theoretically possible to skip constructor invocation altogether, which
would of course eliminate the need to pass any constructor arguments in.
This would require some changes to CGLIB, and probably there aren't too
many classes out there that you'd want to proxy and are Serializable but
don't have a default constructor, but I thought I'd throw this out there.
