> The constructor for {{BlockReceiver.PacketResponder}} says
> {code}
>       final StringBuilder b = new StringBuilder(getClass().getSimpleName())
>           .append(": ").append(block).append(", type=").append(type);
>       if (type != PacketResponderType.HAS_DOWNSTREAM_IN_PIPELINE) {
>         b.append(", downstreams=").append(downstreams.length)
>             .append(":").append(Arrays.asList(downstreams));
>       }
> {code}
> So it includes the list of downstreams only when it has no downstreams.  The {{if}} test
should be for equality.
