A DESCRIPTION OF THE PROBLEM :
When I use an AffineTransform which includes both rotation and scaling to derive a new Font instance, and then use that Font instance to draw text to a Graphics2D, the text does not draw. It seems like I can get the text to draw if I reduce the scale, though (e.g. from 12 to 10).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a Font, derive a new Font using a rotated + scaled AffineTransform, draw text on a Graphics2D using that derived Font.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The text is drawn to the graphics.
ACTUAL -
The text is not drawn to the graphics.
