I also had image scaling problems using AffineTransform's except I wasn't
getting an exception. My problem was the image display was 'corrupt'. Sun
were aware of this problem and suggested using drawImage to do the scaling.
I also had strange problems using this but I haven't verified exactly what's
going on. I'll post my findings when I have them.
In short, it seems image scaling is 'a bit flakey' in places :(
