A collection with cascade=\"all-delete-orphan\"was no longer referenced by the owning entity instance: com.htsc.thfx.framework.entity.user.UserInfo.authorities; nested exception is org.hibernate.HibernateException: A collection with cascade

@Entity
public class UserInfo implements Serializable {

    @Id
    @Column(length = 50)
    private String username;// 



    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = true)
    @JoinColumn(name = "username", foreignKey = @ForeignKey(name = "none", value = ConstraintMode.NO_CONSTRAINT))
    private Set authorities = new HashSet();


}

새 set만 낡은 set로 바꿀 수 없습니다. 이렇게 안전하게 삭제해야 합니다.

            List save = userAuthorityDao.save(newList);
            // jpa  
            if (userInfo.getAuthorities() == null)
                userInfo.setAuthorities(new HashSet<>());
            userInfo.getAuthorities().clear();
            userInfo.getAuthorities().addAll(save);
