Hibernate nao filtra registros

@Entity
@Table(name = "Usuarios")
public class Usuario implements Serializable {

	@Id
	@Column(name = "id_usuario", nullable = false)
	@GeneratedValue(strategy = GenerationType.AUTO)
	private Integer id_usuario;

	@Column(name = "login", nullable = true)
	private String login;

	@Column(name = "senha", nullable = true)
	private String senha;

	@ManyToOne(fetch=FetchType.EAGER)
	@JoinColumn(name = "id_Empresa")
	private Empresa empresa;

}

O metodo da classe DAO que faz a busca:

    public List<T> findByTeste(final T example)  {
        Criteria criteria = getSession().createCriteria(example.getClass());
        criteria.add(Example.create(example));
        final List<T> result = criteria.list();
        return result;
    }
