The doc for DragSourceDragEvent says nothing about the ctor's behavior
if input 'dsc' == null.
The doc says:
public DragSourceDragEvent(DragSourceContext dsc,
int dropAction,
int actions,
int modifiers)
Constructs a DragSourceDragEvent. This class is typically
instantiated by the DragSourceContextPeer rather than directly
by client code.
Parameters:
dsc - the DragSourceContext that is to manage
notifications for this event.
dropAction - the value of one of the static fields from
DNDConstants indicating the type of user drop action
this event represents.
actions - the value of one of the static fields from
DNDConstants indicating the type of target drop action
supported by and returned from the current drop target.
modifiers - specifies the state of the input device
modifiers associated with the user gesture.
