Hi Tobias,
Welcome to Fedora.
Hey and Thanks. :)
I would recommend you joining Java SIG [1], where you can find help
with
packaging, reviews, bugfixes etc. We have IRC channel and mailing list
where you can communicate with us.

Thanks also for this tip, I'll be there regularly.
* I'm used to gpg-sign my git commits/tags by default. Should I
continue this practice while packaging? I've read somewhere that some people don't
want that, therefore my question.
We generally don't do that in Fedora.
Okay.
