On the Mac this sanity test was failing on German and French keyboards prior to these changes. The test is part of a key logger app I created.

On the French keyboard the digits are shifted but I assumed we would still want those keys to map to KeyCode.0-9 as they do on Windows. My solution was to hard-code those key positions to be digits but this interferes with Dvorak layouts. I'm tweaking the implementation to fix this. The new approach will be to query both the shifted and unshifted characters on a key and favor digits and letters over everything else (and something over nothing).

(I've been writing Mac code to enumerate all the OS keyboard layouts and generate lists showing which Java key codes will change from the historic implementation. It also does some sanity checking.)
