FULL PRODUCT VERSION :
jdk1.7.0_03
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]
A DESCRIPTION OF THE PROBLEM :
One touch expandable button of JSplitPane will reduce the vertical scroll bar value by 15 if vertical scroll bar is scrolled to maximum value and then, clicked one-touch Expandable button to minimise the left pane.
Anyone can verify this by seeing GUI where scroll bar position is changed. Same can also be verified using console output.
REPRODUCIBILITY :
This bug can be reproduced always.
