The GroupMetadataManager one should be working for you with 0.9. I don’t have a 0.9 KCC set up at the moment, so I’m using an 0.8 version where it’s different (it’s the other class for me). The only thing I can offer now is did you put quotes around the arg to --formatter so you don’t get weird shell interference?
