I'm using 3.6.10.Final

there is an annoying quirk that causes you to have to declare your unique constraints in terms of logical names whenever you have an IdClass
instead of physical names when you don't.

How can you set things up so that you are express your uniqueConstraints in terms of physical and not logical names?

note: all other constraints I have defined are in terms of the @column annotation's name property.

It is working using Embedded and from what I've since this is the only way it works reliably in this release of Hibernate.
