Disabled JRadioButtonMenuItems and JCheckBoxMenuItems are not drawn correctly by Swing. There are actually two problems. The first problem is the text is not drawn with the 3-d disabled look. The selected icon is also not drawn disabled.
 The first problem is caused because the paintText method in
WindowsRadioButtonMenuItemUI and WindowsCheckBoxMenuItemUI do not override the paintText method like WindowsMenuItemUI does.

Sample Code:

import java.awt.Point;
import java.awt.event.ActionEvent;
import java.awt.event.WindowEvent;

import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import javax.swing.JRadioButtonMenuItem;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
