*            or a path to an html file or SVG image file e.t.c

public static void openInBrowser(String url)
{
    try
        {
            URI uri = new URL(url).toURI();
            Desktop desktop = Desktop.isDesktopSupported() ? Desktop.getDesktop() : null;
            if (desktop != null && desktop.isSupported(Desktop.Action.BROWSE)) {
                desktop.browse(uri);
            } else {
                throw new Exception("Desktop not supported, cannout open browser automatically");
            }
        }
    catch (Exception e)
        {
            /*
             *  I know this is bad practice 
             *  but we don't want to do anything clever for a specific error

            e.printStackTrace();

            // Copy URL to the clipboard so the user can paste it into their browser
            StringSelection stringSelection = new StringSelection(url);
