spec for methods:
dragDropEnd(DragSourceDropEvent dsde),
dragEnter(DragSourceDragEvent dsde),
dragExit(DragSourceEvent dsde),
dragOver(DragSourceDragEvent dsde),
dropActionChanged(DragSourceDragEvent dsde)
is unclear about behavior if input parameter==null.
Currently all methods throw NullPointerException except
dragDropEnd(DragSourceDropEvent).
More convenient behavior here is to throw NullPointerException
for null parameters for all these methods or else it should be
figured in spec.

Here is what doc says:
