Accelerators - odd behavior

It seems to me that this is working as designed. You have created two 
different KeyCombinations and asked that both fire your runnable. 
Further, both of the KeyCombinations match your key input since both a 
KeyPressed and a KeyTyped event are sent when pressing a key that has an 
associated character. I'm not sure how we could change it in a way that 
wouldn't be surprising or difficult to specify or document.
