> Issue only exists in the Headless platform. Consider this test code:

>
> KeyCombination combination = KeyCombination.valueOf("shortcut+,");
>
> KeyEvent event = new KeyEvent(KeyEvent.KEY_PRESSED, "s", "S", KeyCode.S,
> false, true, false, false);
> boolean match = combination.match(event);
>
>
> What happens is that the KeyCombination is an instance of
> `KeyCharacterCombination`.
>
> `KeyCharacterCombination` is special, because in its `match` function, it
> will call:
> `Toolkit.getToolkit().getKeyCodeForChar(getCharacter(), code));`
> which will be delegated to the `HeadlessApplication`, which will throw an
> `UnsupportedOperationException`.
>
> Most of the time, the `KeyCombination` is not an instance of
> `KeyCharacterCombination`, so this exception can only be reproduced with more
> special combinations like in the example with the comma.
>
> I used the implementation we also use in `Monocle`. Rechecked with the US
> keyboard layout.
