I can confirm that it does work in linux. I'm currently using X-Plane 10.45 in Mint Linux Cinnamon version 17.3. I had a full installation in Windows 10 and then installed X-Plane in linux. I then copied the Aircraft, Custom Scenery and Resources folders from Windows to linux. I have a mix of JARDesign and FlightFactor airliners and I just had to activate them all first time. Do NOT forget to reload the plane after activation!
Once all this is done, everything works. So the only thing JARDesign haven't done is write an install routine for linux!
