      FULL PRODUCT VERSION :


      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows XP [Version 5.1.2600]

      A DESCRIPTION OF THE PROBLEM :
      java version "1.5.0_06"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
      Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Add a property change listener to a component.
      Invoke setCursor.
      No property change is fired.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Since the cursor is as much a property of a component as the background color, I would expect a property change to be fired when the cursor is changed.

      I was implementing a visual overlay with a non-opaque component (like a badge icon or tinting effect, see rabbit-hole.blogspot.com/2006/04/decoratoroverpainter-update.html). The overpainter's cursor must match the underlying component's cursor to avoid cursor flicker or obscuring the underlying component's cursor altogether.
      ACTUAL -
      No property change is fired.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      CUSTOMER SUBMITTED WORKAROUND :
      Recompile source for Component to include the line

      firePropertyChange("cursor", oldCursor, newCursor)
