<h3 dir="auto">Environment</h3>
<ul dir="auto">
<li>Dubbo version: 2.7.2</li>
<li>Operating System version: win7</li>
<li>Java version: Java1.8</li>
</ul>
<h3 dir="auto">Steps to reproduce this issue</h3>
<p dir="auto">ExtensionLoader类中loadClass(Map&lt;String, Class&gt; extensionClasses, java.net.URL resourceURL, Class clazz, String name)方法</p>
<p dir="auto">....<br>
String[] names = NAME_SEPARATOR.split(name);<br>
if (ArrayUtils.isNotEmpty(names)) {<br>
cacheActivateClass(clazz, names[0]);<br>
for (String n : names) {<br>
cacheName(clazz, n);<br>
saveInExtensionClass(extensionClasses, clazz, name);<br>
}<br>
}<br>
....</p>
<h3 dir="auto">Expected Result</h3>
<p dir="auto">最后一行代码saveInExtensionClass(extensionClasses, clazz, name);中的name应该改成n？<br>
由于dubbo中的name都是一个（没有逗号分隔），所以不会发生问题<br>
例如：<br>
