SDN4 — ошибка сопоставления GraphModel с экземпляром

В моем веб-приложении я храню и аутентифицирую пользователей на сервере Neo4j.

В моем потоке, если я зарегистрируюсь в приложении (таким образом, сохранив экземпляр пользователя), а затем перейду на страницу входа, я смогу войти в систему нормально. Если я остановлю сервер и запущу его снова, я не смогу войти в систему. Ошибка:

org.springframework.security.authentication.InternalAuthenticationServiceException: Error mapping GraphModel to instance of co.foo.data.models.User

Пользователь находится в базе данных. Если я удалю пользователя, снова зарегистрируюсь и войду в систему, он будет работать нормально, пока я не перезапущу сервер, так что это повторяется.

Использование SDN 4.0.0.RC1
