Ah, nice! Does not look like it is working, though. For some reason the __consumer_offsets topic is still empty. I see there's a few debug(..) logging messages that might get displayed if things go wrong - would you know how to get those displayed? (Right now I'm just running as 'java -jar ...' with no logging config).
