Emmanuel Bernard resolved EJB-217:
----------------------------------

    Resolution: Rejected

use @Fetch(SUBSELECT)

> Multiple @OneToMany(fetch=FetchType.EAGER) relationships not supported 
> -----------------------------------------------------------------------
>
>          Key: EJB-217
>          URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-217
>      Project: Hibernate Entity Manager
>         Type: Bug

>     Versions: 3.2.0.cr1
>  Environment: JBoss4.0.4.GA
>     Reporter: Michał Borowiecki

>
>
> 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.
