What about printing the 'img'? Is it a GraphicsNodeRable8Bit?
Since I still can't reproduce the problem (is it possible there is
some sort of build issue?). Can you try adding the following method
into SVGImageElementBridge, and calling it from createRasterImageNode
immediately after the call to readURL: Filter img = reg.readURL(purl,
extractColorSpace(e, ctx)); printFilterTree(img, "");

protected static void printFilterTree(Filter filt, String pref) {
System.out.println(pref + filt);
java.util.Vector v = filt.getSources();
java.util.Iterator i = v.iterator();
while (i.hasNext())
printFilterTree((Filter)i.next(), pref+" ");
}

Yup.

Yup.

Yup, more specifically if the Filter (or chain of Filters) has
this property set then the source image is a stand-in for an
unavailable image.

what do you mean by 'a default'? The only place this is set in my
code base is in SVGBrokenLinkProvider and it is always given a value
of the SVGDocument to use.
