Multiple @OneToMany(fetch=FetchType.EAGER) realized by List not supported
-------------------------------------------------------------------------

                 Key: EJB-304
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-304
             Project: Hibernate Entity Manager
          Issue Type: Bug
    Affects Versions: 3.2.0.cr1
         Environment: JBoss4.0.4.GA
            Reporter: Morten Andersen-Gott


Having more than one relationship on en entity annotated with @OneToMany(fetch=FetchType.EAGER) causes exception when deploying the ejb3 module:
org.hibernate.HibernateException: cannot simultaneously fetch multiple bags.

This bug is thoroughly explained here:
http://www.jroller.com/page/eyallupu?entry=hibernate_exception_simultaneously_fetch_multiple

and depends on HHH-1718 "Have multiple bag fetches revert to subselect fetching for all but one of the bags"

The temporary solution in HHH-1413 - disallowing multiple bag fetches is unsuitable to ejb3 environment, because the spec does not disallow it.
