JavaFX MenuItem.setAccelerator( ) not working - javafx-2

Question

I want my JavaFX program to be able to dynamically change the accelerator for menu items. However, I can't seem to get it to work in JavaFX 2.2. In the code below, the first menu item has an accelerator "Ctrl+M" and it works fine. "Ctrl+M" is printed every time the menu item is selected using a mouse or with the keyboard accelerator Ctrl+M. The second menu item attempts to change the first men item's accelerator to "Ctrl+L". After choosing the second menu item, I can click on the first menu item again and it shows that its new accelerator is "Ctrl+L", but I cannot use the keyboard accelerator Ctrl+L to activate the first menu item. Instead, I still need to use Ctrl+M to activate the first menu item. Any suggestions on what is going wrong here?

Dynamically changing the accelerator has iffy behaviour at present, but this is a bug which has been fixed for 8u20:
