MacOS X 10.7.4 macmini4,1 etc.
Run for instance the attached test. You'll see various components, a first of them is TextField. Drag from there. On other platforms, you'll see that cursor will be always the same while dragging, even if every component has its own cursor set explicitly.

On Mac, however, the cursor will change on every component. Why, the drag process will not start at all, it seems.

We understand that on Mac people virtually do not use AWT widgets any more. However technically it is a bug.
