        final InputStream is = new FileInputStream(input);
        final CompressorInputStream in = new GzipCompressorInputStream(is, true);
        TarArchiveInputStream tin = new TarArchiveInputStream(in);
        TarArchiveEntry entry = tin.getNextTarEntry();
        while (entry != null) {
            File archiveEntry = new File(dir, entry.getName());
