That's because there's not "menuBar.font" key in the UIManager class, it should be:

UIManager.put("MenuBar.font", f);

i.e. Caps are important or:

UIManager.put("MenuItem.font", f);

for each JMenuItem's font

Here's a list of these properties

EDIT: Added mcve

I don't see where it's not working, if I run this code, it works fine for me

import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

public class UIManagerFontChangeExample {
    
    private JFrame frame;
    private JLabel label;
    private JMenuItem item1, item2;
    private JMenu menu;
    private JMenuBar bar;
    
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                Font f = new Font("sans-serif", Font.PLAIN, 12);
                UIManager.put("Menu.font", f);
                UIManager.put("MenuItem.font", f);
                UIManagerFontChangeExample example = new UIManagerFontChangeExample();
                example.createAndShowGui();
            }
        });
    }
    
    public void createAndShowGui() {
        frame = new JFrame("Font changing example");
        label = new JLabel("This is a label");
        bar = new JMenuBar();
        menu = new JMenu("Menu");
        item1 = new JMenuItem("Item1");
        item2 = new JMenuItem("Item2");
        
        menu.add(item1);
        menu.add(item2);
        bar.add(menu);
        
        frame.add(label);
        frame.setJMenuBar(bar);
        
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}

Before changing font:

After changing font:

The code I added above is called: Minimal, Complete and Verifiable Example, next time, please post a valid one, the same I did, so we can copy-paste, I didn't use an actionListener because the question isn't related to the actions, but the font. Or Icon because it's not related either, I did a full example code that you can copy-paste and see how it works, without modifying anything, that's what you were asked for.

For the MenuBar font you need to call:

UIManager.put("Menu.font", f);

And for the MenuItem

UIManager.put("MenuItem.font", f);
