You missed the big discussion on fedora-devel apparently. Short version is that
Workstation working group proposed disabling the firewall, which FESCo
rejected, so instead that made a firewall with all ports allowed, which FESCo
approved, or at least declined to disapprove.

I think socket activation would be the best way to go. It would solve two
problems: listening on public address, and startup synchronization.

When I wrote comment #c93, I didn't know that upstream is sympathetic to doing
socket activation. It might not be trivial with Java, but this would be the
perfect solution in the long run.
