     * For Linux we require an exact match of distro and version to
     * use the preconfigured file.
     * If synthesising fails, we fall back to any preconfigured file
     * and do the best we can. For the commercial JDK this will be
     * fine as it includes the Lucida fonts. OpenJDK should not hit
     * this as the synthesis should always work on its platforms.
