yep, it is done that way, you may check poms if you want. It wasn't that
simple with jersey, but I managed to get usable results from what we
have now; the script I posted previously is used mainly for coverage
info collection and report generation. If you have some experience
and/or want to suggest some improvement, feel free to do so.

JIRA issues with patches is good way how to start, you might get write
access to svn after few added tests (we just need to have chance to
review your work, check whether tests don't break anything.. simply -
gain mutual trust).
