ClassCastException when using annotations alpha 4

When I execute "new AnnotationConfiguration().configure().buildSessionFactory();" the following exception occurs:

java.lang.ClassCastException: [Lorg.hibernate.cfg.Ejb3Column;

Any ideas?

This turns out to be caused by the fact that I used a @Column annotation with a @ManyToOne annotation instead of @JoinColumn as expected.

Can someone from the Hibernate team please revisit this issue and ensure that Hibernate throws a cleaner error message?

This is an alpha quality release and I currently don't manage user error.

I understand but should I file a RFE for future releases?
