You can't use transport.fetch() for LsRemote. LsRemote should only be
looking at the remote peer... fetch() not only looks, but also copies
the remote repository locally, depending upon the RefSpecs you have
added to the collection it uses.

Instead you need to use:

  Collection<Ref> refs;
  FetchConnection fc = transport.openFetch();
  try {
    refs = fc.getAdvertisedRefs().values();
  } finally {
    fc.close();
  }

and then loop through the refs collection to find the names that are
relevant for output.
