    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(baos);
    Dictionary dictionary = new LRUDictionary();
    dictionary.init(Short.MAX_VALUE);
    byte[] blahBytes = Bytes.toBytes("blah");
    Compressor.writeCompressed(blahBytes, 0, blahBytes.length, dos, dictionary);
    dos.close();
    byte[] dosbytes = baos.toByteArray();
    DataInputStream dis = new DataInputStream(new ByteArrayInputStream(dosbytes));
    dictionary = new LRUDictionary();
    dictionary.init(Short.MAX_VALUE);
    byte[] product = Compressor.readCompressed(dis, dictionary);
    assertTrue(Bytes.equals(blahBytes, product));
