This bug applies to other Swing components like JButton, JCheckBox....
Mnemonics underscore fails to display under arabic characters that
extends below the text base line causing the Mnemonics underscore to
overlap the designated character

To reproduce bug:
1- Compile and run the following code
2- Observe the Mnemonics underscore under Arabic chracters.
3- Verify that underscore overlaps characters that extends below the text base line
