> Will change logic in the ReferenceableHandler. Per my experience with
> Referenceable so far it doesn't make sense to inject a UUID property into the
> object, as it can be calculated on demand with fairly trivial overhead. So
> ReferenceableHandler will no longer be a listener that injects UUID, but
> rather its 'getReferenceable' method will return UUID calculated from
> ObjectId on the fly.
> This also fixes a bug - an exception when extracting UUID from a HOLLOW
> object, since we can read ObjectId of a HOLLOW object without inflating it
> form DB.
> Finally @Referenceable annotation is no longer needed and can be removed from
> Cayenne. After all every single object in Cayenne has ObjectId and hence we
> can produce a UUID for it. The only current purpose of @Referenceable is
> therefore to provide UUID as a property (which is not that useful). End users
> who would still like to inject UUID in their objects, can declare their own
> annotation and their own listener.
