Does this work when entity is a proxy?
I'd like an integration test, that ensures it has a proxy an based on that tests the isNew method.

I don't understand why it's related to proxy, could you expand?

The entity might be a Hibernate proxy. And I basically don't trust any code to properly work with those. Just the normal paranoia after working with JPA to much.

I'm not expert of proxy, as far as I know, proxy only take care of accessing lazy attributes and associations, version is not in that case, and this PR only reuse the existing code wrapper.getPropertyValue(it.getName()) to get value of version to refine the logic.
