Arabic FATHATAN combining mark misplaced when using drawString / TextLayout

FULL PRODUCT VERSION :
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b05)
Java HotSpot(TM) Client VM (build 22.1-b02, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
When drawing text on a Graphics2D instance to which a TRANSFORM HAS BEEN APPLIED, the positioning of combined glyphs may be wrong.
This is the case for the following string:
\u062A\u0644\u0642\u0627\u0626\u064A\u0627\u064B
where the Arabic FATHATAN character (u064B) which is combined with \u0627 is positioned with a different transform than the rest of the output string. The glyph should be just above the other glyph. Instead the position seems to be subject to the current transformation matrix and depends on e.g. the scaling and rotation of the graphics object.

The error occurs, if the TextLayout object is constructed for a graphics instance to which a transform has already been applied.
It does not occur, if the TextLayout object is constructed for a graphics instance which has been reset to the identity transform. I.e. if I apply the transform after the TextLayout object for the text has been created and draw the TextLayout object after applying the transform, the mark will be positioned correctly. This workaround only works for drawing with TextLayout (or using the GlyphVector) only. drawString() will always fail in that respect.

The problem was noticed as significant difference in output when a document containing the above mentioned arabic text was printed.

I found at least one bug referring to misplaced ligature marks in Arabic text, but this has been marked as fixed.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and execute the example below or try to draw the above mentioned string on a scaled Graphics2D canvas using the drawString method (or TextLayout).

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
TextLayout should position all glyphs correctly. Not only "most of them".

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
reset the transform currently applied to the Graphics2D instance. Create the TextLayout instance for the text to be output and restore the previous transform before drawing the textlayout.
