FULL PRODUCT VERSION :
1.4.2_10

ADDITIONAL OS VERSION INFORMATION :
WindowsXP SP2

A DESCRIPTION OF THE PROBLEM :
When I click a JSlider on the left side of the knob,
it doesn't move and the value is not changed.

When I click it on the right side of the knob,
it moves correctly.

This problem occurs with the follwing parameters.
- Maximum: 50
- Minimum: 0
- Snap To Ticks: true
- Minor tick spacing: 10

According to BasicSliderUI.java:397,
You use Math.round() to compute a snaped value.

But in this case default moving unit is 5 ( (max - min) / 10 ).
So the value is always rounded to upper value.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create a JSlider on any form.
2. set follwing parameters to the JSlider
   - max: 50
   - min: 0
   - setSnapToTicks() : true
   - minor tick spacing: 10
3. run the program
4. click on the left side of the knob.
5. nothing happens(THIS iS THE PROBLEM!)


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When I click on the left side of the knob,
the knob (and actual value) should be changed.

ACTUAL -
The knob (and actual value) does not changed.


REPRODUCIBILITY :
This bug can be reproduced always.
