@Reference注解使用mock="return null"属性报错

[a601942905git]

在测试本地伪装的时候，在@Reference注解中使用mock="return null"属性会出现ClassNotFoundException异常，而在xml配置文件中使用mock="return null"就没有问题，难道注解不支持嘛？

@a601942905git I tried to verify it on 2.6.5-SNAPSHOT, it works as expected.

See below for what I changed:

ps, your samples looks good. Are you interested in building https://github.com/dubbo/dubbo-samples together, to show all Dubbo's features as many as possible, and as simple as possible?
