Hi Jani, good to see you around and you are still interested in your baby
Currently only Herwin (cvs login harsens) is working on ODEJava. I have restructured and improved it a little in the past. But I think that's it, regarding contributions in the last years.
Currently there is no actual alternative imo. jBullet, while very promising, still has issues with joints (no translational axes, rotational not that flexible), JOODE is very incomplete, jPhysX... well I don't like PhysX
, and so on.
We are using ODEJava as most important implementation for jME Physics 2.
Re your proposals: Tutorial would surely be great. Having the binaries precompiled for the development version is nice, yes. I tried to provide those (with jME community help) in the past. At least for the releases this was successful. But if you don't have all the platform available yourself it's a pain to make them for the development version each time you change the natives.
I'd be happy to discuss ODEJava's future
