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.

That's the purpose of the test but it fails to test it.
You've just found another proof that multiple L&Fs can't be used concurrently. I've been talking about it since [the very start of this code review](https://github.com/openjdk/jdk/pull/25907#pullrequestreview-2953647827).
When you change L&F, all the `UIDefaults` of the old L&F are removed and values for the newly installed L&F are added.
If a component or its UI doesn't store a setting, such as color, font or icon, in its field, the setting is retrieved from `UIDefaults` — but the values are different now.
This is what happens in the current test without any changes. After Windows L&F is installed, the L&F is switched back to the whatever L&F was initially. As the result, there are no check marks and bullets in Windows L&F.
The test has to re-create its UI after testing for a L&F is complete. Such a scenario isn't supported by `PassFailJFrame` at the moment, see [JDK-8357455](https://bugs.openjdk.org/browse/JDK-8357455) and https://github.com/openjdk/jdk/pull/24439#discussion_r2100038079. There's no easy workaround.
The test doesn't receive events from `PassFailJFrame`, so the needs to be a custom UI, or the test should be run several times for different L&Fs.
