java.awt.image.ColorModel.getPixelSize() was changed to be final in 1.2.

JLS 13.4.16 expects vm to throw VerifyError if subclasses from 1.1.x that override getPixelSize are loaded (unconfirmed). I would expect javac to throw error if source for 1.1.x subclass is compiled with 1.2 classes.

Same effect for
 - java.awt.image.DirectColorModel.getPixelSize()
 - java.awt.image.IndexColorModel.getPixelSize()
