OrderBy does not work in java

I have the following structure: a contract, has several additives so I have my contract class and my additive class

In the contract class, I call it:

@OneToMany(mappedBy = "contrato", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
private List<Aditivo> aditivo;

I just need this list to be sorted by date field so I changed to

@OneToMany(mappedBy = "contrato", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
@OrderBy("data ASC")

But when I do this it gives error

JBAS014777:   Services which failed to start:      service jboss.persistenceunit."contratos.war#contratos": org.jboss.msc.service.StartException in service jboss.persistenceunit."contratos.war#contratos": Failed to start service

I've tried @OrderBy (name="date") tb

MY ADDITIVE ENTITY: then have getters and setters

@Entity
@Table(name="aditivo",schema="contratos")
public class Aditivo implements Serializable{
private static final long serialVersionUID = 2379719760666156224L;

@Id
@GeneratedValue
private Long id;

@Column(length = 300)
private String tipo;

@Column
private Boolean pdf;



public Boolean getPdf() {
    return pdf;
}

public void setPdf(Boolean pdf) {
    this.pdf = pdf;
}

@Column
private Date data;

@Column(length = 300)
private String numero;

@Column(length = 500)
private String objeto;

@ManyToOne
@JoinColumn(name="contrato", referencedColumnName = "id")   
private Contratos contrato;
