      Description



      Name: skT45625 Date: 06/14/2000


      java version "1.3.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      This bug shows up when using MatteBorder with a tiled icon.
      The problem is because the paintBorder() method uses setClip() which does not
      take into account the current clipping area. Replacing setClip() with
      clipRect() will fix the problem.

      /*
       * If you resize the frame to a size smaller than the inner panel,
