  222         int scaleX = (int)tx.getScaleX();
  223         int scaleY = (int)tx.getScaleY();
  224         DataBufferInt buffer = new DataBufferInt(scaleX * width * 
scaleY * height);

   The fix is in the shared code and the scale factor can have floating 
point value on Windows. (for example 1.5).
   It is better to round the final width and height after scaling them.

   Thanks,
   Alexandr.
