java Exception class

[fangyincheng]

What would you like to be added:

 Can it support Java exception classes？

Why is this needed:

When dubbo-go's returns an exception, java need decode as Throwable.

java code:

Object obj = in.readObject();
if (obj instanceof Throwable == false)
     throw new IOException("Response data error, expect Throwable, but get " + obj);
setException((Throwable) obj);
setAttachments((Map<String, String>) in.readObject(Map.class));

@fangyincheng I think it's supported. you can define a POJO with a field detailMessage and set the JavaClassName to java.lang.Throwable. Please have a try. Expecting your result!

@wongoo Exception is in java SDK, so I thinks it should not be feeled by user. Should it be supported in hessian?

[wongoo]
