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.
