> 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.
