I created a program to create a calendar as an svg image and it works just fine when I run it on windows, however when run on a mac it just creates an empty svg file. Can someone please help me figure out what is going on?

public void getSVG() throws IOException
    {
        DOMImplementation imp = SVGDOMImplementation.getDOMImplementation();
        String s = SVGDOMImplementation.SVG_NAMESPACE_URI;
        SVGDocument doc = (SVGDocument) imp.createDocument(s, "svg", null);
        SVGGraphics2D svgGen = new SVGGraphics2D(doc);
        String ss = findFile().getAbsolutePath();
        Writer out = new FileWriter(ss);
        this.paint(svgGen);
        svgGen.stream(out, true);
        out.flush();
        out.close();
    }

I haven’t tried much of anything, as it works just fine on windows. I don’t know why it would be different on mac.
