It should read

    /**
     * Closes this channel.
     *
     * <p> This method, which is specified in the {@link AbstractChannel} class
     * and is invoked by the {@link java.nio.channels.Channel#close close}
     * method, first cancels all of this channel's keys. It then invokes the
     * {@link #implCloseSelectableChannel implCloseSelectableChannel} method in
     * order to perform the actual work of closing this channel.
     * </p>
     */

This change is required in order to fix 4458268.
