java – JPA查询的奇怪错误

@Override
    public List<HorarioAtencion> findByPeriodo(Person person,int dia,int mes,int anno) {
        Query busqueda = em.createNativeQuery("Select * from HorariosAtencion where " +
                                              "idPerson = ?1 AND "+
                                              "DAY( fechaInicio) <= ?2 AND MONTH( fechaInicio ) <= ?3 AND YEAR( fechaInicio) <= ?4 AND "+
                                              "DAY( fechaFin) >= ?2 AND MONTH( fechaFin ) >= ?3 AND YEAR( fechaFin ) >= ?4 ORDER BY TIME(fechaInicio)",HorarioAtencion.class);
       busqueda.setParameter(1,person.getId());
       busqueda.setParameter(2,dia);
       busqueda.setParameter(3,mes);
       busqueda.setParameter(4,anno);
       return busqueda.getResultList();
    }

此查询返回结果,但会触发下一个异常：

Caused by: Exception [EclipseLink-6044] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.QueryException

我不知道可能是什么问题：/

更新：
