 * Proxy stream that prevents the underlying input stream from being closed.

     * Creates a proxy that shields the given input stream from being
     * closed.

    public CloseShieldInputStream(InputStream in) {

     * Replaces the underlying input stream with a {@link ClosedInputStream}
     * sentinel. The original input stream will remain open, but this proxy
     * will appear closed.
