Java 从4到5休眠迁移

我已经使用Hibernate 4很长时间了，现在我需要升级到Hibernate 5，我现在遇到一些命名查询的问题：

ERROR:   HHH000177: Error in named query: findByNumHeure
org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [ch.plugin.plugin.entity.Reservation]. Expected arguments are: ch.plugin.plugin.entity.Reservation, long [SELECT new Reservation(r, COUNT(r.numeroReservation)) FROM ch.plugin.plugin.entity.Reservation r WHERE r.numeroReservation =:num and r.reservationPK.heureDebutReservation = :heure GROUP BY r.numeroReservation HAVING r.reservationPK.heureDebutReservation = min(r.reservationPK.heureDebutReservation)]

@NamedQuery(name = "findByNumHeure", query = "SELECT new Reservation(r, COUNT(r.numeroReservation)) FROM Reservation r WHERE r.numeroReservation =:num and r.reservationPK.heureDebutReservation = :heure GROUP BY r.numeroReservation HAVING r.reservationPK.heureDebutReservation = min(r.reservationPK.heureDebutReservation)"),

这是我的命名查询：

ERROR:   HHH000177: Error in named query: findByNumHeure
org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [ch.plugin.plugin.entity.Reservation]. Expected arguments are: ch.plugin.plugin.entity.Reservation, long [SELECT new Reservation(r, COUNT(r.numeroReservation)) FROM ch.plugin.plugin.entity.Reservation r WHERE r.numeroReservation =:num and r.reservationPK.heureDebutReservation = :heure GROUP BY r.numeroReservation HAVING r.reservationPK.heureDebutReservation = min(r.reservationPK.heureDebutReservation)]

@NamedQuery(name = "findByNumHeure", query = "SELECT new Reservation(r, COUNT(r.numeroReservation)) FROM Reservation r WHERE r.numeroReservation =:num and r.reservationPK.heureDebutReservation = :heure GROUP BY r.numeroReservation HAVING r.reservationPK.heureDebutReservation = min(r.reservationPK.heureDebutReservation)"),

当然，我有一个构造函数：

public Reservation() {
}

public Reservation(Reservation reservation, Long etat) {
    this.reservationPK = reservation.getReservationPK();
    this.couleurReservation = reservation.getCouleurReservation();
    this.iDRecurrence = reservation.getIDRecurrence();
    this.isPaye = reservation.getIsPaye();
    this.numeroReservation = reservation.getNumeroReservation();
    this.responsable = reservation.getResponsable();
    this.texte = reservation.getTexte();
    this.etat = etat.intValue();
    this.prix = reservation.getPrix();
}

所以我的问题是：为什么它在Hibernate4中工作得很好，而现在它在Hibernate5中不再工作了？代码完全一样
