The old code also request the state of the different keys like shift, 
control, etc. And after the fix we lose this information, probably we 
should apply it on top of the modifiers?

Another unclear thing is that we use 
java_awt_event_InputEvent_BUTTON1_DOWN_MASK which is a mask for 
InputEvent as modifier for ActionEvent which does not have such mask.
