JPA/Hibernate延迟加载无法正常工作

我有一个关于hibernate延迟加载的复杂问题。我拥有以下4个实体：简历->认证、简历->经验、简历->教育：

@Table(name = "CV", schema = "recruiter")
public class CV extends TrackingEntity {


@Column(name = "RAW_FILE")
@Lob
private byte[] rawFile;

....

@OneToMany(fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private Set<Experience> experiences = new HashSet<Experience>();

@OneToMany(fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private Set<Education> educations = new HashSet<Education>();

@OneToMany(fetch = FetchType.LAZY, cascade = { CascadeType.ALL })
private Set<Certification> certifications = new HashSet<Certification>();

....

}

有人知道这里发生了什么吗？它将实体与子insert语句一起持久化，然后刷新实体并从数据库中选择子体验、证书等：

为什么Hibernate要执行select语句，因为这正是我试图通过延迟加载避免的？

在测试集合是否已初始化时，情况更是如此：persistenceUnitUtil.isLoadedcv，certifications；->符合事实的persistenceUnitUtil.isLoadedcv，体验；->错误的persistenceUnitUtil.isLoadedcv，教育；->错误的
