I notice that com/sun/image is missing from my OpenJDK7 clone, i.e. it's not in the classes directory or the rt.jar files in the two image directores (jre and jdk). Also the demo itself isn't in the OpenJDK7 tree. Both the demo and the com/sun/image directory /are/ in the binaries installed with the latest 117 installer, i.e. jdk-7-ea-bin-b117-windows-i586-04_nov_2010.exe.
