foo.stg that imports bar.stg, both from jar, doesn't work from top level dir.

[parrt]

This method strips foo.stg but then looks up parent as jar:file:/.../my.jar!.

    @Override
    public URL getRootDirURL() {
        //System.out.println("url of "+fileName+" is "+url.toString());
        String parent = Misc.stripLastPathElement(url.toString());
        try {
            return new URL(parent);
        }
        catch (MalformedURLException mue) {
            errMgr.runTimeError(null, null, ErrorType.INVALID_TEMPLATE_NAME,
                                mue, parent);
        }
        return null;
    }
