使用Hessian呼叫過載方法報異常問題，例如：

String SayHello();
	
String SayHello(String name);

客戶端呼叫上面的方法：

IHello hello = (IHello) hessianProxyFactory.create(IHello.class, url);
 String result = hello.SayHello();
 log.info("ClientTest1 返回結果："+result);

 result = hello.SayHello("tom");
 log.info("返回結果："+result);

呼叫第一個方法是ok,呼叫第二個方法後會報異常:

org.springframework.web.util.NestedServletException: Hessian skeleton invocation failed; nested exception is com.caucho.hessian.io.HessianProtocolException: 
   .......
 Caused by: com.caucho.hessian.io.HessianProtocolException: SayHello: expected end of call ('z') at 0x53 (S).  
   .....
 com.caucho.hessian.client.HessianRuntimeException: com.caucho.hessian.io.HessianProtocolException:
  .......
