My first guess would be that somehow the Image decoders aren't
being bootstrapped properly. Or perhaps when you hand off your
fake 'svg:image' element to the base class something isn't right

public void RasterImageNode.setImage(Filter newImage)
In conjunction with:
import org.apache.batik.ext.awt.image.red.CachableRed;
import
org.apache.batik.ext.awt.image.red.BufferedImageCachableRed;
import org.apache.batik.ext.awt.image.rable.Filter;
import org.apache.batik.ext.awt.image.rable.RedRable;
CachableRed red;
red = new BufferedImageCachableRed(buffered_image);
Filter f = new RedRable(red);

As long as you are tied into the SVG -> GVT stuff through the
bridge you shouldn't have to worry to much about the rebuild stuff...
