================================================
Mantis Version: rc b23:
Testing OS : Solaris Sparc 9 (japanese)
             RH Linux 8.0 (japanese, American English)
             Windows XP professional(japanese)
L&F : GTK
Locale : ja
=================================================

JCheckBoxMenuItem/JRadioButtonMenuItem doesn't have the button's frame, so if there is no default checked item, only the name of the items are seen in the menu.

To reproduce,

1)Extract attached file(JMenuTest.tar)
2)Compile all java files.
3)Launch JMenuTest
4)Select GTK in L&F menu
5)Click either of the menu, JCheckBoxMenuItem or JRadioButtonMenuItem.
You can see only the items' name and you don't know which menu items exist.
6)Select one of the item on either of JCheckBoxMenuItem or JRadioButtonMenuItem.
The item selected is checked and you can know which menu items exist, but the buttons don't have the frame, so it looks different from other L&F.

You can see this problem on Font2D demo's Menu(RadioButton).

This problem is reproducible with Mantis beta also.
