Не удалось создать SessionFactory, когда я использую @Type (type = "org.hibernate.spatial.GeometryType") в объекте

Я пытаюсь сохранить географические данные в БД, для этого я учусь использовать hibernate-пространственный, но у меня возникают некоторые проблемы с фабрикой сеансов.

Проблема возникает, когда всущность, которую я использую @Type (type = "org.hibernate.spatial.GeometryType"), класс Hibernate Util завершается ошибкой.

Это DAO: 

@Repository
public class GeometryDAO implements IGeometryDAO {

    Session session;
    Transaction tx;

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public void registerPoint(String userId, String point) {
        startsOperation();

        Points pointEntity =new Points();

        pointEntity.setPointName("test");
        pointEntity.setUserId("12345");

        pointEntity.setPoint((Point) wktToGeometry(point));

        session.save(pointEntity);

        tx.commit();

        session.close();
    }

    public Object getPoints() {

        StringBuilder queryStB = new StringBuilder();

        queryStB.append("SELECT * FROM Points");

        String queryString = queryStB.toString();
        Query query = entityManager.createNativeQuery(queryString);
        return query.getResultList();
    }

        private void startsOperation() throws HibernateException {
        session = HibernateUtil.getSessionFactory().openSession();
        tx = session.beginTransaction();
    }

    private Geometry wktToGeometry(String wktPoint) {
        WKTReader fromText = new WKTReader();
        Geometry geom = null;
        try {
            geom = fromText.read(wktPoint);
        } catch (ParseException e) {
            throw new RuntimeException("Not a WKT string:" + wktPoint);
        }
        return geom;
        }

}

Это HibernateUtilКласс: 

import java.util.HashMap;
import java.util.Map;

import org.hibernate.SessionFactory;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;

import com.gisapp.models.entity.Points;
import com.gisapp.models.entity.User;

public class HibernateUtil {
private static StandardServiceRegistry registry;
  private static SessionFactory sessionFactory;

  public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
      try {
        StandardServiceRegistryBuilder registryBuilder = 
            new StandardServiceRegistryBuilder();

        Map<String, String> settings = new HashMap<>();
        settings.put("hibernate.connection.driver_class", "org.postgresql.Driver");
        settings.put("hibernate.connection.url", "jdbc:postgresql://localhost:5432/postgres");
        settings.put("hibernate.connection.username", "postgres");
        settings.put("hibernate.connection.password", "admin");
        settings.put("hibernate.show_sql", "true");
        settings.put("hibernate.hbm2ddl.auto", "update");
        settings.put("hibernate.dialect", "org.hibernate.spatial.dialect.postgis.PostgisDialect");

        registryBuilder.applySettings(settings);

        registry = registryBuilder.build();

        MetadataSources sources = new MetadataSources(registry);



        sources = new MetadataSources(registry)
                .addAnnotatedClass(Points.class).addAnnotatedClass(Points.class);

        Metadata metadata = sources.getMetadataBuilder().build();

        sessionFactory = metadata.getSessionFactoryBuilder().build();
      } catch (Exception e) {
        System.out.println("SessionFactory creation failed");
        if (registry != null) {
          StandardServiceRegistryBuilder.destroy(registry);
        }
      }
    }
    return sessionFactory;
  }

  public static void shutdown() {
    if (registry != null) {
      StandardServiceRegistryBuilder.destroy(registry);
    }
  }

} Это сущность:

    this.pointName = pointName;
}

public Geometry getPoint() {
    return point;

public void setPoint(Geometry point) {
    this.point = point;
}
}

В DAO происходит сбой по методу startOperation-> session = HibernateUtil.getSessionFactory (). OpenSession (), но я не понимаю, почему.
