title: Having ActionEvent called when Radio Button is not selected
body: <p>I've noticed that ActionEvent would still be triggered within my group of <code>JRadioButtonMenuItem</code> even when specifying the conditional statement:</p>
  
  <pre><code>if(!button.isSelected())
      //Do stuff
  </code></pre>
  
  <hr>
  
  <pre><code>defaultTheme = new JRadioButtonMenuItem("Default theme");
      defaultTheme.addActionListener(new ActionListener() {
          @Override
          public void actionPerformed(ActionEvent e) {
              if(!defaultTheme.isSelected())  
                  System.out.println("temp");
          }
      });
  </code></pre>
  
  <hr>
  
  <p>I have multiple theme options within my settings menu, however if a say <em>(say default)</em> is already selected, I don't want to execute any redundant code if the default menu is already selected and the user clicks on the already selected Radio Button.</p>
