When I Extends DefaultRevisionEntity, the eclipse compiler gives me the following error : The return type is incompatible with DefaultRevisionEntity.getId()

This is The class:

package br.com.siq.gqfweb.sistema;

import javax.persistence.Entity;

import org.hibernate.envers.DefaultRevisionEntity;
import org.hibernate.envers.RevisionEntity;

@Entity
@RevisionEntity(AuditoriaRevEntityListener.class)
public class AuditoriaRevEntity extends DefaultRevisionEntity {


}
