SVG doc won't render when loaded as an input stream

Hi,

I'm having trouble loading a SVG document from an InputStream. My
document is perfectly loaded and rendered inside Squiggle but it won't
render when I try to load it as an input stream in my app using
SAXSVGDocumentFactory. Here is an extract from my code and the error
stack. My SVG document contains a gradient definition and a use tag that
seems to be the reason of the failure (see the attached file).

public void loadSVG(InputStream inputStream)
{
          String parser = XMLResourceDescriptor.getXMLParserClassName();
          SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser);
          Document document = factory.createDocument(null, inputStream);

          svgCanvas.setSVGDocument((SVGDocument) document);
}


An I/O error occured while processing the URI '#MyGradient' specified on
the element <rect>

Any help appreciated,
