> Assignee: Till Rohrmann
>
> The {{RpcEndpoint.start}} and {{RpcEndpoint.shutDown}} methods should be
> allowed to throw exceptions if things go wrong. Otherwise, exceptions will be
> given to a callback which handles them later, even though we know that we can
> fail the components right away (as it is the case for the {{TaskExectuor}},
> for example).
