 * equivalent to passing {@link #copy}a

 * <code>java.io.BufferedOutputStream</code> to {@link #copy}, and
 * flushing the output stream afterwards. The streams are not closed after
 * the copy.

 * @param source      The InputStream to obtain data from.
 * @param destination The OutputStream to copy data to.
 * @throws IOException if IO error
