Don't take this as an expert opinion, but since subclasses contain all
member fields of the superclass, I'd expect that a subclass needs to
have a changed SerialVersionUUID if the superclass changes.
Testing this aspect might be in order.
My question would be: test what? In the real world are SerialVersionUUID
particularly useful for Cayenne entities? With Cayenne ROP, I've never seen any
code in Hessian which pays any attention to the version. Is this more useful
with a cluster of application servers and different instances running different
versions of the code? Are there are specific use cases where Cayenne entities
would be involved?
