After updating to hibernate \>= 7.1.9, I get the following error:

One weird thing is that in my Quarkus application, the bug happens ~50% of the time: When you start the application, the exception will either always be thrown or never; it’s decided at startup and stays consistent. However, in the minimal reproducible example below, the exception is always thrown.

```java
@DomainModel(
        annotatedClasses = {
                ParentEntityB.class,
                ChildEntityB.class,
                ChildEntityA.class,
                ParentEntityA.class,
        }
)
@ServiceRegistry(
        settings = {
                @Setting(name = AvailableSettings.SHOW_SQL, value = "true"),
                @Setting(name = AvailableSettings.FORMAT_SQL, value = "true"),
        }
)
@SessionFactory
class ORMUnitTestCase {
    @Test
    void multipleEntitiesSameTableCascadeAll(SessionFactoryScope scope) {
        scope.inTransaction(session -> {
            ParentEntityA parentEntityA = new ParentEntityA("id");
            ChildEntityA childEntityA = new ChildEntityA(parentEntityA);
            parentEntityA.addChild(childEntityA);
            session.persist(parentEntityA);
            session.flush();
        });

        scope.inTransaction(session -> {
            ParentEntityA terminal = session.find(ParentEntityA.class, "id");
            terminal.getChildren().forEach(childEntityA -> childEntityA.setFlag(true));
        });
    }
}

@Entity
@Table(name = "PARENT")
class ParentEntityA {

    @Id
    @Column(name = "ID", nullable = false)
    String id;

    @OneToMany(mappedBy = "parent", cascade = ALL)
    private final Set<ChildEntityA> children = new HashSet<>();

    public ParentEntityA() {}

    public ParentEntityA(String id) {
        this.id = id;
    }

    public void addChild(ChildEntityA child) {
        children.add(child);
    }

    public Set<ChildEntityA> getChildren() {
        return children;
    }

    public String getId() {
        return id;
    }
}

@Entity
@Table(name = "CHILD")
class ChildEntityA {

    @EmbeddedId
    private ChildId childId;

    @ManyToOne
    @MapsId("parentId")
    @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID")
    private ParentEntityA parent;

    @Column(name = "FLAG", precision = 1)
    private boolean flag;

    public void setFlag(boolean flag) {
        this.flag = flag;
    }

    public ChildEntityA() {}

    public ChildEntityA(ParentEntityA parent) {
        this.parent = parent;
        this.childId = new ChildId(parent.getId());
    }
}

@Embeddable
class ChildId {

    @Column(name = "PARENT_ID", nullable = false)
    private String parentId;

    public ChildId() {}

    public ChildId(String parentId) {
        this.parentId = parentId;
    }
}

// The entities B exist (and are registered in the DomainModel) but are not used
@Entity
@Table(name = "PARENT")
class ParentEntityB {

    @Id
    @Column(name = "ID", nullable = false)
    String id;

    @OneToMany(mappedBy = "parent")
    private final Set<ChildEntityB> children = new HashSet<>();

    public ParentEntityB() {}
}

@Entity
@Table(name = "CHILD")
class ChildEntityB {

    @EmbeddedId
    private ChildId childId;

    @ManyToOne
    @MapsId("parentId")
    @JoinColumn(name = "PARENT_ID", referencedColumnName = "ID")
    private ParentEntityB parent;

    public ChildEntityB() {}
}

```

It seems that it has been introduced by [HHH-18860](https://github.com/hibernate/hibernate-orm/commit/a04f801aa16eb27a44ea20fbf26f276774313b63). I get the same error with 7.1.24, 7.2.12 and 7.3.2. Last working version is 7.1.6.

I created an atlassian account for this but I am not been able to create an issue so I write here instead.

Is this expected but just not enforced in the older version or is this a bug ?

This is a bug. Please try to create a reproducer with our [test case template](https://github.com/hibernate/hibernate-test-case-templates/blob/master/orm/hibernate-orm-7/src/test/java/org/hibernate/bugs/JPAUnitTestCase.java) and if you are able to reproduce the issue, create a bug ticket in our [issue tracker](https://hibernate.atlassian.net) and attach that reproducer.
