After migration from hibernate 5.6.12.Final to 6.X.X.Final, following model stopped working:

```auto
@Entity
public class Person {

    @Id
    @Column(name = "USER_ID")
    private String userId;

    @OneToOne(optional = false, fetch = FetchType.EAGER)
    @Fetch(FetchMode.JOIN)
    @JoinColumn(name = "USER_ID", referencedColumnName = "USER_ID")
    private Employee employee;
}

```

```auto
@Entity
public class Employee implements Serializable {

    @Id
    @Column(name = "USER_ID")
    private String userId;

    @Column(name = "PARTNER_ID")
    private Long partnerId;

    @OneToMany(fetch = FetchType.EAGER)
    @Fetch(FetchMode.JOIN)
    @JoinColumn(name = "PARTNER_ID", referencedColumnName = "PARTNER_ID")
    private List<Roles> roles;
}

```

```auto
@Entity
public class Roles implements Serializable {
    
    @Id
    @Column(name = "PARTNER_ID")
    private Long partnerId;
    
    @Id
    @Column(name = "CODE")
    private String code;
    
    @Column(name = "NAME")
    private String name;
}

```

When launching application face following error:

```auto

```

Issue is reproducable on version 6.0.0.Final, 6.2.2.Final and also tried latest 6.4.4.Final. Can you please assist with this problem?
