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.

One more thing I observed is "If we change the order of menu creation" then the icons rendered are different.
For e.g. if the order is

    menuBar.add(createMenu("javax.swing.plaf.metal.MetalLookAndFeel",
                "Metal"));
        menuBar.add(createMenu("com.sun.java.swing.plaf.windows.WindowsLookAndFeel",
                "Windows"));
        menuBar.add(createMenu("com.sun.java.swing.plaf.motif.MotifLookAndFeel",
                "Motif"));

then the icons are 
![Windows_Second_Pos](https://github.com/user-attachments/assets/81efec22-b3b2-48e2-a31b-f095c8ec4c3f)

and when Windows L&F is at last pos then rendered icons are
![Windows_Last_Pos](https://github.com/user-attachments/assets/6b13bfb8-c319-4344-afd7-26584f3a2056)

Shouldn't the icons for the L&Fs be same ?
