> When an AMQP 1.0 link (producer/consumer) is detached/closed by the broker
> with an error, clients must send a response Detach frame. If the link context
> was not set before the error occurred, this leads to the broker experiencing
> an NPE while processing the reply and then stopping the entire connection.
