Hibernate query "or condition" won't work

I am trying the following hibernate query but it always gives me a wrong result:

    @SuppressWarnings("unchecked")    @Override    public List<Jcelulasmin> getAllOthers(int id, String username) {        Session session = this.sessionFactory.getCurrentSession();        List<Jcelulasmin> JcelulasList = session.createQuery("from Jcelulasmin where jgrelhas.id=? and (jconcorrentes is null or jconcorrentes.users.username <> ?) order by id").setParameter(0, id).setString(1, username).list();        for(Jcelulasmin p : JcelulasList){            logger.info("Jcelulas List::"+p);        }        return JcelulasList;    }

This query returns me 13 values, but that should be the result of "jconcorrentes.users.username <> ?"

The result of "jconcorrentes is null" is 47 values so my query should return 47+13=60...

I'm trying to achieve the following SQL query that actually returns 60 values:

SELECT * FROM `jcelulas` WHERE GrelhasId=1 and (ConcorrentesId is null or ConcorrentesId<>1) 

ps:jconcorrentes.id is 1 so the sql and hql should be the same

Table/Entitiy definition:

@Entity@Table(name = "jconcorrentes", catalog = "7jogos")public class Jconcorrentes implements java.io.Serializable {    private Integer id;    ....    private Users users;@ManyToOne(fetch = FetchType.EAGER)    @JsonBackReference    @JoinColumn(name = "username", unique = true, nullable = false)    public Users getUsers() {        return this.users;    }    public void setUsers(Users users) {        this.users = users;    }

I tried the following and it actually worked:

session.createQuery("from Jcelulasmin where jgrelhas.id=? and (jconcorrentes is null or jconcorrentes <> 1) order by id").setParameter(0, id).list();

The only problem is that i have to get it by username which is in Users.

Users:

@Entity@Table(name = "users", catalog = "7jogos", uniqueConstraints = @UniqueConstraint(columnNames = "username"))public class Users implements java.io.Serializable {@NotEmpty(message="Não se esqueça do Email")@Email(message="Email Inválido")private String username;...private Set<Jconcorrentes> jconcorrenteses = new HashSet<Jconcorrentes>(0);@OneToMany(fetch = FetchType.EAGER, mappedBy = "users")    public Set<Jconcorrentes> getJconcorrenteses() {    return this.jconcorrenteses;}public void setJconcorrenteses(Set<Jconcorrentes> jconcorrenteses) {    this.jconcorrenteses = jconcorrenteses;}
