FULL PRODUCT VERSION :
java version  " 1.7.0_21 "

Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Mac OS X 10.7.5

A DESCRIPTION OF THE PROBLEM :
Rotated String is drawn to the opposite direction on Mac OS X.
When we rotate graphics by g.rotate(?Math.PI / 2) and g.drawString( " ABC " ),  " B "  should be drawn upper  " A " . But  " B "  is drawn under  " A " .  " C "  is drawn under the  " B " .

REGRESSION.  Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the program to test
2. Check the shown window

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
90 degrees rotated  " ABC123 "  should be shown.
ACTUAL -
Rotated  " 321CBA "  is shown at the wrong position.

REPRODUCIBILITY :
This bug can be reproduced always.

                RotatedStringFrame frame = new RotatedStringFrame();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setSize(200, 400);
                frame.setVisible(true);
            }
        });
    }
}

CUSTOMER SUBMITTED WORKAROUND :
We can avoid this bug by using drawString(AttributedStringIterator) instead of drawString(String).
