Ошибка загрузки класса с Spring Boot и Hibernate 5

Недавно я обновил приложение на основе Spring Boot с Hibernate 4 до Hibernate 5. С тех пор я наблюдаю проблему с загрузкой классов. Очевидно, что классы гибернации и класс моего домена загружаются двумя разными загрузчиками классов. Это происходит только в том случае, если я запускаю приложение с помощью Spring DevTools и Hibernate 5. Комбинации DevTools/Hibernate 4, mvn spring-boot:run/Hibernate 5 работают.

Проблему можно воспроизвести с помощью следующего простого приложения весенней загрузки (полный проект eclipse доступен здесь)

@Entity
public class Employee implements Serializable {
    private static final long serialVersionUID = 1L;

    private Long     id;
    private String   firstName;
    private String   lastName;

    public Employee() {  
    }

    public Employee(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    @Id @GeneratedValue
    public Long getId() {
        return id;
    }

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

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String toString() {
        return id + ": " + lastName + ", " + firstName;
    }
}

public class AppConfig {

    @Autowired
    private DataSource dataSource;

    @SuppressWarnings("serial")
    @Bean
    public LocalSessionFactoryBean sessionFactory() {

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setPackagesToScan("problem.domain");
        sessionFactory.setHibernateProperties(new Properties() {
            {
                setProperty("hibernate.dialect", "org.hibernate.dialect.DerbyTenSevenDialect");
                setProperty("hibernate.hbm2ddl.auto", "create-drop");
                setProperty("hibernate.current_session_context_class", "thread");
            }
        });

        return sessionFactory;
    }
}

@Component

        Employee empl = new Employee("John", "Doe");
        session.persist(empl);
        tx.commit();
    }
}

Запуск этой программы с помощью Spring DevTools приводит к следующей ошибке:
