Re: [eclipselink-users] Undetected problem mapping fields to columns

Your classes are not correctly mapped. As you deliberately placed
@Column-annotations on the offending class members, I am not sure what you
are aiming at.

Please file an enhancement request, if you think, there should have been
some sort of validation error message while bootstapping the EMF.
