spec for constructor
java.awt.dnd.DroptargetDragEvent(DragSourceContext dsc, Point p,
                                 int dropAction, int srcActions)
says nothing about range of valid values for 'dropAction' and 'srcActions'.
Currently constructor accepts:
DnDConstants.ACTION_NONE,
DnDConstants.ACTION_COPY,
DnDConstants.ACTION_MOVE,
DnDConstants.ACTION_LINK for 'dropAction'
and 'srcActions':
'srcActions' & ~(DnDConstants.ACTION_COPY_OR_MOVE | DnDConstants.ACTION_LINK).
For any other ints constructor throws IllegalArgumentException.

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

public DropTargetDragEvent(DropTargetContext dtc,
                           Point cursorLocn,
                           int dropAction,
                           int srcActions)

      Parameters:
