The extension is using a java gps framework which can be found here http://javagps.sourceforge.net/ and should work as smoothly as in 2004 (at least I hope so) as soon as the serial input is brought back to life. Though there might be problems with changes between jump 1.1.1 & the recent openjump... but I'll take care of that then.
