No, JPA does not support this (yet). Read the spec before opening bug reports.

> 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?
