При запуске приложения Spring Boot появляется следующая ошибка. Я предполагаю, что это как-то связано с моими Отношениями из одного класса в оба моих дочерних класса (Employee, ClientUser) общего подкласса (MyUser).

Это классы сущностей. сопоставленный суперкласс: 

@MappedSuperclass
public abstract class IdentifiableEntity {
@Id
@NotNull
@GeneratedValue
@Column
private UUID id;

public IdentifiableEntity() {
}

public IdentifiableEntity(UUID id) {
    this.id = id;
}

public UUID getId() {
    return id;
}

public void setId(UUID id) {
    this.id = id;
}
}

родительский класс: 

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class MyUser extends IdentifiableEntity {
@Column
private String name;
@Column
private String email;
@Column
private String phoneNumber;
@Column
private String password;
@Column
private Role role;

public MyUser() {
}
//getters and setters omitted
}

первый ребенок 

@Entity
public class Employee extends MyUser {
@Column
private String address;
@Column
private String image;
@OneToMany(mappedBy = "employee")
private List<Appointment> appointments;

public Employee() {
}
//getters and setters omitted
}

второй ребенок 

@Entity
public class ClientUser extends MyUser {
@OneToMany(mappedBy = "clientUser")
private List<Appointment> appointments;

public ClientUser() {
}
//getters and setters omitted
}

обе ссылки указаны в другой таблице 

@Entity
public class Appointment extends IdentifiableEntity {

@ManyToOne
private Employee employee;

@ManyToOne
private ClientUser clientUser;

public Appointment() {
}

//getters and setters omitted
}

У меня была такая же проблема. Я узнал, что в моих классах сущностей была проблема. Я использовал BigInteger для управления версиями. 

@Version
private BigInteger version

Я изменил на Integer, и проблема была решена.

Возможно, вызвано ошибкой в ​​hibernate 5.2.14: hibernate.atlassian.net/browse/HHH-12332. Обновление до 5.2.15 или до последней версии должно исправить это.
