Apache FOP: Image not found after packing resources into jar

I have problems with my Apache FOP application.

Everything worked fine, until I started to pack external files (xsl, ttf, ...) from an external working directory into the jar file of the application. Since then, no images are loaded anymore and I get the following error:

FOUserAgent - Image not available. URI: data:image/jpeg;base64,.... 
Reason: org.apache.xmlgraphics.image.loader.ImageException: The file format is 
not supported. No ImagePreloader found for data:image/jpeg;base64,...(No context info available)
org.apache.xmlgraphics.image.loader.ImageException: The file format is not supported. No ImagePreloader found for data:image/jpeg;base64

In the xsl file, the images are embedded with:

<fo:external-graphic xsl:use-attribute-sets="helpicon" 
  fox:alt-text="helpicon" 
  src="url('data:image/jpg;base64,...I'm the base64 encoded image data...')">   
</fo:external-graphic>

Why are images not working anymore, when I pack the files into the jar? The images are embedded as a base64 string into the xsl file, so the image data must be available...

Thanks :)

Edit 1 I'm setting the FopFactory base url with:

    String path = MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath();
    String decodedPath = URLDecoder.decode(path, "UTF-8");
    File jar = new File(decodedPath);

    fopFactory.setBaseURL(jar.getParent());

and this is my ClasspathUriResolver:

public class ClasspathUriResolver implements URIResolver {

@Override
public Source resolve(String fileName, String base) throws TransformerException {

    System.out.print(" RESOLVING: " + fileName);

    URL url = getClass().getClassLoader().getResource(fileName);
    StreamSource jarFileSS = new StreamSource();

    System.out.println(" TO: " + url.toString());

    try {
        InputStream jarfileIS = url.openStream();
        jarFileSS.setInputStream(jarfileIS);
    } catch (IOException ioExp) {
        throw new TransformerException(ioExp);
    }
    return jarFileSS;
}

I checked the log from the ClasspathUriResolver, included files (fonts, stylesheets) get resolved correctly.
