title: JInternalFrame not using JFrame L&F in Netbeans 7.1.2
body: <p>I'm creating a MDI application with Netbeans, everything's working well as expected with the Look and Feel set to Nimbus. </p>
  
  <p>Anytime I run the application, the JFrame and its toolbars use the specified L&amp;F (Nimbus) but the Internal Frames use the cross platform (Metal) L&amp;F making the application look shabby. </p>
  
  <p>I want the Internal Frames to use the same L&amp;F as the JFrame. Please how do I fix this?</p>
  
  <p>I've tried calling <code>JFrame.setdefaultlookandfeeldecorated(true)</code> and <code>SwingUtilities.updatecomponenttreeui(frame)</code> but they didn't solve the problem.</p>
