在将Quarkus 2.16迁移到3（以及Hibernate 5.6迁移到6）之后，我在持久化数据方面遇到了一个bug。基本上，我的schema看起来像这样：

@Entity
class Person {
    @Column(name = "name")
    private String name;
    @OneToMany(
            mappedBy = "owner",
            cascade = CascadeType.ALL,
            orphanRemoval = true,
            fetch = FetchType.EAGER
    )
    private Set<Pet> pets = new HashSet<>();
}

@Entity
class Pet {
    @Column(name = "name")
    private String name;
    @JoinColumn(name = "fkidperson",
                referencedColumnName = "id")
    @ManyToOne(optional = false)
    private Person owner;
    @OneToMany(mappedBy = "pet",
               cascade = CascadeType.ALL,
               orphanRemoval = true,
               fetch = FetchType.EAGER)
    private Set<Food> foods = new HashSet<>();
}

@Entity
class Food {
    @Column(name = "name")
    private String name;
    @JoinColumn(name = "fkidpet",
                referencedColumnName = "id")
    @ManyToOne(optional = false)
    private Pet pet;
}

我会尝试用POST请求更新它，

{
    "id": 2,
    "name": "John",
    "pets": [
        {
            "id": null,
            "name": "Fuffy",
            "foods": []
        }
    ]
}

而在后端，我想用entityManager.merge(person)覆盖前一个人，但失败了，

org.hibernate.AssertionFailure: null identifier for collection of role (Pet.foods)

在它工作之前。有什么想法吗？谢谢！
