FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

EXTRA RELEVANT SYSTEM CONFIGURATION :
IBM 3 button scrollpoint optical mouse, with IBM MouseSuite
drivers v 4.31.

A DESCRIPTION OF THE PROBLEM :
The Scrollpoint mouse has a force sensor instead of a
traditional wheel. The scrolling speed depends on the
pressure applied to the stick.
This mouse works without problems in native Windows widgets
(for instance in internet explorer), where it even provides
360 degrees scrolling.
It also works well with Mozilla, which uses a custom widget
set (although only vertical scrolling is available).

BUT: In any Java application, when a light upwards pressure
is applied to the stick, the scrolling occurs in the wrong
direction. A stronger pressure produces a normal scrolling.
Any downwards pressure gives the expected result.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Launch a Java app. which displays a JScrollPane.
2. Apply a light upwards pressure to the mouse stick


EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: the page should scroll up.
Observed: the page scrolls down.

REPRODUCIBILITY :
This bug can be reproduced always.
