John:

Does that work when you run it on your linux box?  Because on my windows 
xp it shows all of the menu items greyed out.  JMenuItem doesn't keep 
the disabled foreground color in the its field.  The colors are 
extracted from the UIManager when the component is repainted so if you 
reset the value of MenuItem.disabledForeground anywhere it will paint 
all of them with that color.
