A DESCRIPTION OF THE PROBLEM :
drawGlyphVector method fails to draw japanese unicode characters.

REGRESSION. Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the testcase provided and print to a printer. Look at the printer output.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected the characters to print as they appear on screen.
ACTUAL -
The Japanese characters print fine but anything after the last Japanese character in a string is garbage. All subsequent print operations are garbled / ignored.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
extract glyph shapes from the glyph vector and fill the shape in graphics context.
