将Apache Mina从2.0.21升级到2.1.3后，ldap测试出现问题

如何解决将Apache Mina从2.0.21升级到2.1.3后，ldap测试出现问题

我有一个包含apache mina的项目，我使用apacheds，spring-ldap-test进行测试， 我将Apache Mina从2.0.21升级到2.1.3 当我运行测试类时，我得到以下信息：

Exception in thread "pool-4-thread-1" java.lang.NoSuchFieldError: SESSION_SECURED

这是完全正常的，这是由于最新版本的Apache Mina发生了变化 [https://mina.apache.org/mina-project/2.1-vs-2.0.html]， 将apapds库升级到最新版本并不能解决问题， 这是我的pom.xml：

<dependency>
            <groupId>org.springframework.ldap</groupId>
            <artifactId>spring-ldap-test</artifactId>
            <version>2.3.2.RELEASE</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.directory.server</groupId>
            <artifactId>apacheds-core</artifactId>
            <version>1.5.5</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.directory.server</groupId>
            <artifactId>apacheds-protocol-ldap</artifactId>
            <version>1.5.5</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.directory.server</groupId>
            <artifactId>apacheds-protocol-shared</artifactId>
            <version>1.5.5</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.apache.directory.server</groupId>
            <artifactId>apacheds-server-jndi</artifactId>
            <version>1.5.5</version>
            <scope>test</scope>
        </dependency>

在我看来，这是一个apaches和apache mina兼容性的问题，即使使用最新版本的apacheds，我也想知道是否有什么办法可以解决此问题，请先感谢。
