The Font on JMenuBar is different when the Look And Feel is WindowLookAndFeel and WindowClassicLookAndFeel.

For reproducing this problem, run the attached sample test

- Choose the Windows L&F on the JComboBox on the extreme left
- Click on the "Get Font Details"

All the Components displayed on the JFrame got printed on the Console. The JMenuBar's Font is Segoe UI Font, which is different from the other Component's Font Dialog.
