I am working on an open-source application called FrontlineSMS which can be interfaced with GSM modems to send and receive SMS. The windows installer that is available through their website works fine. Since i wanted to modify it, I got the source code and built the jar and tried to launch it. When I plug in the GSM modem and launch the application, it sometimes detects the GSM device and i am even able to send and receive SMS. Or else 1.) I get the following error-
