Spring Data Neo4j не проходит тестовую настройку junit

Я оцениваю некоторые стеки, обращающиеся к neo4j (2.0.0), и у меня есть некоторые проблемы с пружиной (3.2.6). То, чего я пытаюсь достичь сейчас, очень просто: модульный тест, соединяющий граф и читающий узел. Мой контекст приложения выглядит так:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"
    xsi:schemaLocation="

    http://www.springframework.org/schema/data/neo4j/spring-neo4j.xsd">

    <context:annotation-config />
    <context:spring-configured />
    <context:component-scan base-package="net.vhite.kin">
        <context:exclude-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <tx:annotation-driven mode="proxy" />

    <neo4j:config graphDatabaseService="graphDatabaseService" />
    <bean id="graphDatabaseService"
        class="org.springframework.data.neo4j.rest.SpringRestGraphDatabase">
        <constructor-arg index="0" value="http://192.168.201.2:7474/db/data" />
    </bean>
</beans>

Сам тест тоже довольно прост:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"test-context.xml"})
public class NeoTest {

    @Autowired
    Neo4jTemplate template;

    @Test
    @Transactional
    public void persistedMovieShouldBeRetrievableFromGraphDb() {
        // still empty yet
    }
}

Запуск этого (пустого) теста завершается неудачно при создании контекста приложения. Было много ошибок, до которых мне удавалось устранить, в основном путем исправления дерева зависимостей, но эту я не понимаю. Исключение говорит мне, что узел недоступен, но я еще не отправил ни одного запроса! Так что это как-то связано с инициализацией. Понятия не имею почему. Я погуглил все исключения в этом следе и не нашел хорошего намека.

Последнее, что я сделал, это добавил API проверки (1.1.0). Я использую Spring 3.2.6 с Spring-Data 3.0.0, это может быть проблемой?

Это проблема версии.

SDN 3.0.M01 поддерживает только Neo4j 2.0-M06, после этого произошли значительные изменения API, следующая версия SDN 3.0.RC1 будет поддерживать Neo4j 2.0 и должна быть выпущена 27 января 2014 года.
