Review comment:
which instruction can throw this exception ? is it possible that it is
throws inside the inner loop ?
in that case we could end the loop prematurely .
that do you think ?

> I tried to run `DiscoveryExample` to simulate service discovery, when I first
> entered list to see the list of registrations, I found that the process
> exited directly, I checked the code and found that the code threw
> `NoNodeException` but it was ignored.
> I think if there is no service registered, using `list` should tell me that
> no service is registered instead of just ignoring the exception and closing
> the connection, so I am asking this question, what do you think?
