        ByteArrayOutputStream out = new ByteArrayOutputStream();
        ObjectOutputStream oos = new ObjectOutputStream(out);

        oos.writeObject(code);

        ObjectInputStream ois = new ObjectInputStream(new ByteArrayInputStream(out.toByteArray()));

}

Probably won't work across the wire to a different JVM since it's a dynamically generated class behind the scenes.
