There has been a serious regression in the delivery of dnd events since the
rewrite of the java.awt.dnd package. The DropTarget doesn't get called
anymore when dragging from one Swing component to another. The attached
program can be used to see the behavior. An example operation would be to
drag a color from the color sample area of the color chooser and try to drop
it on the label area at the top of the Transerable inspector (which will
accept any drop).

Dragging within a Swing component (such as within Notepad) does result in
its DropTarget being called, but there is a regression in that behavior as
well as the dragEnter method doesn't get called. This caused a null pointer
exception to be generated. The most recent Swing integration has a workaround
for that problem, but it should be fixed.

The described behavior is seen on the win32 platform.
