Why doesn't my jar file run twice?

Question

I am having problems running the double-click jar file (and open it with java SE), the jar only starts perfectly from the command line, the other banks that I created are launched with a double click.

I exported the jar file using the eclipse exporter, I used the runnable jar export and selected the correct main () class in the launch configuration

When I start the jar using java -jar myjar.jar, it starts, as expected, there will be no exceptions.

I am under linux / windows has the same problem that I do not see the point, because other jar files created by me in the same way, run without any problems.

Just for fun, I created a program ccontaining only

int main(void){
   system("java -jar myjar.jar");
   return 0;
}

When I double-clicked the compiled program c, my can opened!

Here is the MANIFEST

Manifest-Version: 1.0
Class-Path: . libs/commons-compress-1.10.jar libs/zip4j_1.3.2.jar libs/xz.jar libs/commons-io-2.4.jar libs/oat2dex.jar
Main-Class: deodex.Tester

Here is the method main: http://pastebin.com/M8Fhb4qW

package deodex;
import deodex.tools.Logger;
import deodex.ui.LangFrame;
import deodex.ui.Window;
public class Tester {
        public static void main(String args[]) {

        if (Cfg.isFirstLaunch()) {
                    Cfg.setCurrentLang(S.ENGLISH);
                    R.initResources();
                    @SuppressWarnings("unused")
                    LangFrame win = new LangFrame();


        } else {
            Cfg.readCfg();
            R.initResources();
            S.initTempFolders();
            Logger.logToStdIO("[test]" + Cfg.getCurrentLang());

                    @SuppressWarnings("unused")
                    Window win = new Window();



        }

    }
}
