A DESCRIPTION OF THE PROBLEM :
When we start a D&D operation, we use a Drag Image to show the dragged object. The location where this image is shown on screen, is the top left mouse point with java 6. With java 7 it is moved somewhere. An also the mouse drag point is moved.

REGRESSION.  Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just create a drag listener and use the startDrag with an image:

public void dragGestureRecognized(DragGestureEvent dge) {
BufferedImage _image = new BufferedImage(100, 100, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2d = _image.createGraphics();
g2d.setColor(Color.red);
g2d.fillRect(0,0,100,100);
dge.startDrag(DragSource.DefaultMoveDrop,_image, new Point(0, 0),new StringSelection( " test " ), this);



REPRODUCIBILITY :
This bug can be reproduced always.

dge.startDrag(DragSource.DefaultMoveDrop,_image, new Point(0, 0),new StringSelection( " test " ), this);

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use startDrag without Drag Image.
