OS: All tested OS's with RTL locale suppor
testCase: jScrollBar.java

Horizontal JScrollBar's visual behavior is correct and displayed from RTL
if locale is Arabic or Hebrew BUT the calculated value of the
adjustmentListener is LTR, meaning that instead of value "0" at HOME
location it is 280 . The END location value is 0 instead of 280.
