title: Created jar from JRuby file using warbler. Application exit/goes in a blink when run
body: <p>I have created a JRuby desktop application. <a href="https://stackoverflow.com/questions/48223998/how-to-create-distribution-files-exe-with-jruby">Now I need to create installation file for different platforms</a>(Windows, Linux, Mac).</p>
  
  <p>I have created .jar file <a href="https://stackoverflow.com/questions/2269164/create-deployable-jruby-jar-file">using warbler</a>. But when I try to run the .jar, application starts and exit in a blink. It seems application is not crashing as the log says got via <code>java -jar MyApp.jar &gt; log.txt</code>.</p>
  
  <p>Why the application exit, doesn't just stay. Can somebody help me on what I am missing. How I can track the issue?</p>
