Java SE (Java Platform, Standard Edition)

I have a swing timer that logs off a user from the gui after a certain amount of time. When I run the program in Windows it works just as it should.

When I execute the same program in a linux environment it logs off randomly, sometimes after a few seconds, sometimes after a few minutes, and sometimes not at all. It is supposed to logoff after 30mins.

javax.swing.Timer timer = new javax.swing.Timer(logoffTime * 1000 * 60, new ActionListener()   
 {
      public void actionPerformed(ActionEvent evt) 
      {
            timer.stop();    //stop timer
            loginFrame.setVisible(true);  //sends user back to logon page
            conn.close();   // Database Connection
      }
 });

if(logoffTime > 0)
   timer.start();

Any ideas?

Thanks,
Casen
