This bug applies to other Swing components like JButton, JCheckBox....
For RTL Text. The Mnemonic underscore is not displayed under the correct character
in RTL and bidi text. The Mnemonics underscore is displayed under the last
character of the word (Farthest left) instead of the first
character (Farthest right).
To reproduce bug:
1- Compile and run the following code
2- Do "alt+g". Note that English Menu opened
3- Note that the Mnemonics for each JMenuItem is displayed correctly under the first character
4- Try to use the corresponding Arabic or Hebrew Mnemonics for the other JMenus
5- Note that there is no rsponse

in RIGHT_TO_LEFT orientation the LEFT & RIGHT keys work go in the wrong visiual direction.
in the following example when menu "two" is selected the left key should take us to menu "Three" .. instead it goes to "one".
