/**
 * A convenience method that creates a new {@link URI} whose scheme, host, port, path,
 * query are taken from the existing URI, dropping any fragment or user-information.
 * The path is set to "/" if not explicitly specified. The existing URI is returned
 * unmodified if it has no fragment or user-information and has a path.
 *
 * @param uri
 *            original URI.
 * @throws URISyntaxException
 *             If the resulting URI is invalid.
