@OneToMany association in 3.2.0.cr2 does not work with simple element types.
----------------------------------------------------------------------------

         Key: ANN-446
         URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-446
     Project: Hibernate Annotations
        Type: Bug

    Versions: 3.2.0.cr2    
 Environment: Hibernate 3.20.CR4
    Reporter: Mike Brock


Hibernate has always allowed, as far as I can remember to map simple elements as unmapped entities in a OneToMany association (such as Strings, Integers, etc).

In fact, hibernate-annotations 3.2.0.cr1 allowed this:

@OneToMany(targetEntity = String.class) 
private Set<String> roles;

As of this latest release, we get a complaint that String is not a mapped entity.  Is this intentional or a bug?  Previously, hibernate would create a simple two column join table in such an association in a key-value arrangement to deal with this.

I am aware that @CollectionOfElements can be used to deal with this type of association in the hibernate-annotations package.  

Does it's existence imply that the Java Persistence API does not have support for this type of association?
