Bug description ---> JSlider component behaves incorrectly when range limits are near of integer value limits.
****************************************************************************

Platforms:
=============
Windows NT 4.0


JDK, switches Info:
===================
java version "1.3.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-beta-b15)
Java HotSpot(TM) Client VM (build 1.3.1beta-b15, mixed mode)

How to reproduce:
====================
The following program creates frame window which contains 2 JSlider components and 2 JLabel components.
JLabel components show min, max and current values of corresponding JSlider.
The first JSlider has a range of (-2 000 000 000; 2 000 000 000) and the second one has (-100; 100) range and
both of them initially point to it's own max value.


1. Compile and run the following program.
2. Make sure the first JSlider is focused.
3. Push Page Up several times.

You will see the first slider does not stop moving even if max value is reached and the current value of the first slider
is dropped down to the min value after max value is reached.
The second slider is placed on the frame as a sample of correct behavior.
