| When starting a session with an empty hibernate config:
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
.build();
SessionFactory sessionFactory = new MetadataSources(registry)
.buildMetadata()
.buildSessionFactory();
try (Session session = sessionFactory.openSession()) {
session.beginTransaction();
session.getTransaction().commit();
}

(Complete output) Instead of returning an anonymous instance of Dialect, a new `DefaultDialect` class might be a better choice. |
