The channelRead0 method in RpcHandler returns error=null by default in its response.
However, in RpcProxy, response.isError() is used to determine whether an exception should be thrown.
The implementation of response.isError() is shown below:

public boolean isError(){
		return error == null;
	}

This can cause errors even when the operation is executed normally.

这里是中文翻译

在RpcHandler的channelRead0方法中，response默认返回error=null 但是在RpcProxy中，使用response.isError()来是否执行异常，这将会导致正常执行也出错
