[1.1.4] Hotkey doesn't work in runnable jar file --- export as runnable jar currently not available.

I am using SikuliX 1.1.4
I have converted the following code to runnable jar using sikuli IDE:
stop = False
def xHandler(event):
    global stop
    stop = True
Env.addHotkey("x", KeyModifier.CTRL + KeyModifier.SHIFT, xHandler)
while(1):
    mouseMove(50,50)
    wait(1)
    mouseMove(-50,-50)
    wait(1)
    if stop == True:
        exit()

When I execute jar file and press CTRL+SHIFT+x, execution doesn't stop.
But this works fine when I run the code from sikuli IDE
