無法使用蠟染光柵化器將SVG圖像轉換爲PNG

我想使用蠟染光柵化器（蠟染轉碼器1.8）庫將圖像從SVG轉換爲PNG，但即使是簡單的轉換也會引發異常。這是一個示例代碼不工作：無法使用蠟染光柵化器將SVG圖像轉換爲PNG

private static void convertSVGToImage() throws TranscoderException, IOException { 
    String svg_URI_input = Paths.get("caution.svg").toUri().toURL().toString(); 
    TranscoderInput input_svg_image = new TranscoderInput(svg_URI_input); 
    OutputStream png_ostream = new FileOutputStream("caution.png"); 
    TranscoderOutput output_png_image = new TranscoderOutput(png_ostream); 
    PNGTranscoder my_converter = new PNGTranscoder(); 
    my_converter.transcode(input_svg_image, output_png_image); 
    png_ostream.flush(); 
    png_ostream.close(); 
}

哪裏caution.svg是這樣的文件：http://dev.w3.org/SVG/tools/svgweb/samples/svg-files/caution.svg

而且堆棧跟蹤是：

我剛剛通過簡單地使用蠟染1.7.1解決了它。
