EtcdResponsePromise get(), response is not null and no exception happened but throw new IOException

[shengxuanyi]

Details please see the pictures below:

I guess the reason this happened is that the promise is asynchronous, when I debug into the 72 line then the promise object get its value. So here comes a question: anyone know some settings that i am missed to solve this. If no settings for this, whether the waitForPromiseSuccess method can do some improvement to do to prevent this happen?

Fresh one to Etcd4j.
