Notice that the function returns the exception instance, it doesn't raise it. The raising is done in the rest of the internal code.

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

        fi

    # older suse linux distributions do not ship with systemd
    # but do not have an /etc/init.d/ directory
    # this tries to start the fess service on these
    # as well without failing this script
    elif [ -x /etc/rc.d/init.d/fess ] ; then
        /etc/rc.d/init.d/fess stop || true
    fi
    echo " OK"
fi

   * Future} need not be {@linkplain Future#isDone done}, making {@code AsyncFunction} suitable for
   * asynchronous derivations.
   *
   * <p>Throwing an exception from this method is equivalent to returning a failing {@code Future}.
