The spec for ctors

java.awt.dnd.DragGestureRecognizer(DragSource ds)
java.awt.dnd.DragGestureRecognizer(DragSource ds,Component c)
java.awt.dnd.DragGestureRecognizer(DragSource ds,Component c,int)
java.awt.dnd.DragGestureRecognizer(DragSource ds,Component c,int,
                                   DragGestureListener)
does not specify behavior if parameters 'ds'==null or 'c'==null.
Currently ctors throw IllegalArgumentException for 'ds'==null and
ignore 'c'==null.

Here is what doc says:
--------------------------------------------------

protected DragGestureRecognizer(DragSource ds,
                                Component c,
                                int sa,
                                DragGestureListener dgl)

      construct a new DragGestureRecognizer
      Parameters:
        ds - The DragSource for the Component c
        c - The Component to observe
        sa - The source drag actions
        dgl - The DragGestureRecognizer to notify when a gesture is detected
