FULL PRODUCT VERSION :
1.4.1_01, also observed on 1.3.1

FULL OS VERSION :
irrelevant (observed on GNU/Linux 2.4.18 and MacOS X 10.1.5)

A DESCRIPTION OF THE PROBLEM :
The bottom left pixel drawn by javax.swing.plaf.basic.SplitPaneBorder has a different color depending on the orientation of the enclosed JSplitPanel. This appearance is visually inconsistent.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the enclosed test program.

2. Look at the pixel of the very bottom left of the two compartment borders. You might want to use a tool that enlarges the screen.

3. Note its color: orange, the highlight color of the border.

4. On line 44, replace VERTICAL_SPLIT by HORIZONTAL_SPLIT. Compile and run again.

5. Look at the pixel again. Note its color.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The bottom left pixel should always have the same color.
ACTUAL -
The bottom left pixel appears in the shadow color if the JSplitPanel orientation is HORIZONTAL_SPLIT, but in the highlight color if it is VERTICAL_SPLIT. See also

REPRODUCIBILITY :
This bug can be reproduced always.
