I'm looking into packaging kelpie, a flightplanner for flightgear.
This is a mature app, using the eclipse RCP framework. However, it
appears as if this would be the very first eclipse-rcp app in fedora.
(note, not all dependencies are packaged yet, most notably jogl).
Upstream is very responsive, he's made me an ant build script to start
for my communication with him.
I was hoping for some guidance, as I don't have java experience yet.
It's worth noting that jogl was removed from Fedora  because its
licence is explicitly banned. Unless upstream has relicenced jogl to a
better licence it seems likely you may have to submit your package to
