This is because the test after setting WIndows L&F of the menuitem reverts back the Windows L&F to Nimbus L&F via `UIManager.setLookAndFeel(save);` call in the test so when frame is made visible, the L&F resets back to Nimbus L&F resulting in null NimbusIcon.

test/jdk/javax/swing/JMenuItem/RightLeftOrientation.java line 92:

I tried to extend the test (with this PR changes included) for all installed L&Fs and then create the menu for each L&F. 

        UIManager.LookAndFeelInfo[] lafs = UIManager.getInstalledLookAndFeels();
        for (final UIManager.LookAndFeelInfo lafInfo : lafs) {
            System.out.println("installed laf className : " + lafInfo.getClassName());
            System.out.println("installed laf Name : " + lafInfo.getName());
            menuBar.add(createMenu(lafInfo.getClassName(), lafInfo.getName()));
        }

Then the test failed with this exception 

        java.lang.NullPointerException: Cannot invoke "java.awt.Font.hashCode()" because "font" is null
	at java.desktop/sun.font.FontDesignMetrics$MetricsKey.init(FontDesignMetrics.java:213)
	at java.desktop/sun.font.FontDesignMetrics.getMetrics(FontDesignMetrics.java:282)
	at java.desktop/sun.swing.SwingUtilities2.getFontMetrics(SwingUtilities2.java:1235)

Otherwise the RBMI and CBMI does contain the icon after the fix.
