Description

Currently GoCD uses Hibernate 3.6. In order to unblock Spring Framework upgrade to Spring 5+, we need to move to to Hibernate 5. Our current Spring version, 4.3 does support at least Hibernate 5.0 to 5.2 (see here) and maybe later point releases.

If we could get to 5.3 we'd be getting back into a "supported" release, which would be ideal, as long as it works with Spring 4.3. There's nothing in the Spring docs to indicate other 5.x versions wont work.
