sangjian opened a new issue #1894: ExtensionLoader中的loadClass方法这么写不会有并发问题吗？
URL: https://github.com/apache/incubator-dubbo/issues/1894
 
 
   ```java
   else if (isWrapperClass(clazz)) {
       Set<Class<?>> wrappers = cachedWrapperClasses;
       if (wrappers == null) {
           cachedWrapperClasses = new ConcurrentHashSet<Class<?>>();
           wrappers = cachedWrapperClasses;
       }
       wrappers.add(clazz);
   }
   ```
   cachedWrapperClasses有没有可能会被赋值两次，导致第一次的clazz没有加到cachedWrapperClasses中？
