Found this while verifying Dali bug 308271, EclipseLink has the same issue.

@Entity
public class Parent {
    @Id Long id;
}

public class ChildPK implements Serializable {
    private long parent;
}

@Entity
@IdClass(ChildPK.class)
public class Child {
    @Id @ManyToOne
    private Parent parent;
}


Exception Description: The composite primary key attribute [parent] of type [null] on entity class [class model.Child] should be of the same type as defined on its primary key class [model.ChildPK]. That is, it should be of type [long].
