ADDITIONAL OS VERSION INFORMATION :

Microsoft Windows [Version 6.1.7601]


A DESCRIPTION OF THE PROBLEM :
When I use a JTextField with ComponentOrientation.RIGHT_TO_LEFT and horizontal-alighment of JTestField.RIGHT, setting a long text with mixed-direction (Hebrew and English) causes characters to overlap each other, resulting an unreadable layout.


REGRESSION.  Last worked in version 6u43

ADDITIONAL REGRESSION INFORMATION: 
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode, sharing)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the source-code code using java-6 and java-7


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A field showing the hebrew letters in the beginning (right side) and part of the english text in the left-side, with no overlap
ACTUAL -
The english text overlaps the hebrew letters. The result is partly unreadable

REPRODUCIBILITY :
This bug can be reproduced always.
