@font-face like below will not font the font file relative to the CSS file location like other CSS urls do.

@font-face {
    font-family: AFont;
    src: url('fonts/AFontFile.ttf');
}


In StyleManager line 918 there is
            // load any fonts from @font-face
            if (stylesheet != null) {
                faceLoop: for(FontFace fontFace: stylesheet.getFontFaces()) {
                    for(FontFace.FontFaceSrc src: fontFace.getSources()) {
                        if (src.getType() == FontFace.FontFaceSrcType.URL) {
                            Font loadedFont = Font.loadFont(src.getSrc(),10);
                            getLogger().info("Loaded @font-face font [" + (loadedFont == null ? "null" : loadedFont.getName()) + "]");
                            continue faceLoop;
                        }
                    }
                }

This needs to be fixed to resolve urls relative to the stylesheet.
