      Description



      Name: rmT116609 Date: 10/25/2000


      java version "1.2.2"
      Solaris VM (build Solaris_JDK_1.2.2_06, native threads, sunwjit)


      When a JSlider is defined with negative numbers in its range the PageUp and
      PageDown keyboard keys do not work as defined in the Metal Look and Feel
      table. That is, they don't work at all for the slider.

      Sequence to reproduce the problem.
          o) Compile and run the following program.
          o) Activate the slider button by clicking on the thumb tab.
          o) Check that Home, End, and the Arrow keys function properly.
          o) Attempt a block move using the PageUp and PageDown keys.
