I agree it would be good to avoid loading/initializing ObjectStreamClass
(as you say, we have to load ObjectStreamField as the
serialPersistentFields is part of Class, String, and other APIs). My
only concern is that ObjectStreamField doesn't seem to be the right
place for this (as it's concerned with serializable fields) and it's a
bit strange for ObjectStreamClass to call into ObjectStreamField to get
a class signature. Have you considered alternatives, say duplicating
this method, or maybe a ClassSignature class?
