Am I doing something wrong?
Is it possible you are hitting this issue?

P.S. I normally use .png images pretty much exclusively - best to keep things lossless while you are doing image processing work.
I also hit this issue. Switching from OpenJDK to Oracle got me past this specific exception; however, I ran into another problem. When I read a jpg image and save it as a jpg image (yes jpg -> jpg), it comes out as all black when I open it using Ristretto Image Viewer on Xubuntu. When I open it in Firefox, it comes out pink.
From SO comments:
BTW, OpenJDK does have a native JPEG encoder. And if you try to save 32-bit-color file - it fails. And Sun JDK does not fail, but form tinted file. Not sure what is better. – Andrey Regentov Apr 25 '13 at 11:02
If you are getting a pink effect, it is likely because you use a BufferedImage with an alpha-channel while JPG does not support that. Make sure you use a BufferedImage.TYPE_INT_RGB and not BufferedImage.TYPE_INT_ARGB – Guillaume Polet Jul 31 '12 at 13:26
