<ul dir="auto">
<li>Dubbo version: 2.4.9-sp5-20150715</li>
<li>Operating System version: linux</li>
<li>Java version: 1.5</li>
</ul>
<h3 dir="auto">Steps to reproduce this issue</h3>
<ol dir="auto">
<li>在dubbo:refrence 中配置了cache=“LRU”,发现数据无法获取最新数据，有时候取到新的，有时候取到旧的，后来将cache配置删了，发现还是无法解决；</li>
<li>通过调试，用命令trace dubbo接口，发现接口返回的数据中每次都是最新的，但是在程序中debug获取的返回值却是旧的，搞不懂了，为什么会与trace返回的数据不一样呢？</li>
</ol>
<p dir="auto">Pls. provide [GitHub address] to reproduce this issue.</p>
<h3 dir="auto">Expected Result</h3>
<p dir="auto">正常理解是cache去除后，应该是不走缓存？还是说配置问题？<br>
是否会有缓存的序列化的问题，如果有，怎么清除序列化文件？</p>
<h3 dir="auto">Actual Result</h3>
