The bug is reported by EDS PLM Solutions in its development of new J2EE application. They notice different cursors are used in drag-n-drop operations
between native and java applications.

The problem is best illustrated with a java demo program (see the attachment).
This java application always accepts drag:

  public void dragEnter (DropTargetDragEvent event) {
    event.acceptDrag (DnDConstants.ACTION_MOVE);
  }

So you'd expect to see a cursor indicating that a drop is currently allowed when the drag enters and stay over the target window. But when I tries to drag a URL string from Netscape to the java window from its top title ("Drag and Drop Lists") border window, a different cursor is displayed, indicating that a drop is currently not allowed. That's clearly wrong. But it (cursor) looks right as expected if the drag enters the java window from anywhere else.

This only occurs on Sun. It looks OK on Windows.

The following configurations are tested:
Solaris 8, Solaris 8 10/00
Ultra 10, SunBlade 100
Java 1.3, 1.3.1, 1.2.2
