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?
