Duplicated results in Hibernate OneToMany List

I have mapped an 1:N relation with a @OneToMany List, but when I access the list, the results are duplicated due to an OUTER JOIN. This is how the mapping looks like:

@Entity
public class Programmer

    @ElementCollection(fetch=FetchType.EAGER)
    @CollectionTable(name="emails", joinColumns=@JoinColumn(name="id", nullable=false))
    @Column(name="email", nullable=false)
    protected Set<String> emails = new HashSet<String>();

    @OneToMany(mappedBy="programmer", fetch=FetchType.EAGER)
    private List <Game> games = new ArrayList<Game>();

When I get the attribute with prog.getGames(), the results comes duplicated because the Hibernate SQL makes an OUTER JOIN:

from programmer 
left outer join emails on programmer.id=emails.id 
left outer join game on programmer.id=game.id
where programmer.id=?

Is there any solution without transforming the List into a Set? I need to get the games with prog.getGames(), can not use a custom HQL or Criteria.
