[GitHub] [incubator-dubbo] cyejing opened issue #3275: ReferenceBeanInvocationHandler invoke proxy 没有捕获InvocationTargetException
### Environment
* Dubbo version: 2.6.5
* Java version: 1.8
### Steps to reproduce this issue
1. 客户端调用服务端发生异常，异常往上抛
2. ReferenceAnnotationBeanPostProcessor$ReferenceBeanInvocationHandler 代理之后没有catch InvocationTargetException 取得 getTargetException 导致到业务代码之后无法获得到真实的异常
Pls. provide [GitHub address] to reproduce this issue.

### Expected Result
取得真实的异常信息，而不是 InvocationTargetException
### Actual Result
到业务层代码的异常时UndeclaredThrowableException ->cause-> InvocationTargetException ->cause-> 真实的异常
If there is an exception, please attach the exception trace:

@magang0425 这样
```
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
try{
return method.invoke(bean, args);
}catch(InvocationTargetException ite){
throw ite.getTargetException();
}
}
```

@magang0425 我选择重写 ReferenceAnnotationBeanPostProcessor 方法
如@scm1219 的代码。
等新版修复
