报错的意思是javassist的classpool里找不到com.alibaba.dubbo.common.bytecode.proxy1，但是看2.5.3源码，
` // create ProxyInstance class.
String pcn = pkg + ".proxy" + id;
ccp.setClassName(pcn);
ccp.addField("public static java.lang.reflect.Method[] methods;");
ccp.addField("private " + InvocationHandler.class.getName() + " handler;");
ccp.addConstructor(Modifier.PUBLIC, new Class<?>[]{ InvocationHandler.class }, new Class<?>[0], "handler=$1;");
ccp.addDefaultConstructor();
Class<?> clazz = ccp.toClass();
clazz.getField("methods").set(null, methods.toArray(new Method[0]));
// create Proxy class.
String fcn = Proxy.class.getName() + id;
ccm = ClassGenerator.newInstance(cl);
ccm.setClassName(fcn);
ccm.addDefaultConstructor();
ccm.setSuperClass(Proxy.class);
ccm.addMethod("public Object newInstance(" + InvocationHandler.class.getName() + " h){ return new " + pcn + "($1); }");
Class<?> pc = ccm.toClass();
proxy = (Proxy)pc.newInstance();`
pcn 命名为 com.alibaba.dubbo.common.bytecode.proxyX ， X 是原子递增的， ccp.toClass() 会在 classPool 里放入它，接下来 ccm.toClass() 会使用到它，居然因为找不到就报错了？因为公司为了稳定，一直没有升级框架，使用的是当当 dubbox 2.84，底层依赖的是com.alibaba:dubbo:jar:2.5.3

新版本的dubbo 中，javassist生成代理失败后抛出异常后会继续调用jdk生成代理， 所以应该不会出现该问题， 但这个问题总觉得很诡异。
