JInternalFrame not using JFrame L&F in Netbeans 7.1.2

Question

I'm creating a MDI application with Netbeans, everything's working well as expected with the Look and Feel set to Nimbus.

Anytime I run the application, the JFrame and its toolbars use the specified L&F (Nimbus) but the Internal Frames use the cross platform (Metal) L&F making the application look shabby.

I want the Internal Frames to use the same L&F as the JFrame. Please how do I fix this?

I've tried calling JFrame.setdefaultlookandfeeldecorated(true) and SwingUtilities.updatecomponenttreeui(frame) but they didn't solve the problem.
