     * the service (with an 201 status code). It's up to the caller to decide, based on the return
     * value, if he needs to continue sending the room configuration. If {@code null} is returned, the room
     * already existed and the user is able to join right away, without sending a form.
     *
     * @param mucEnterConfiguration the configuration used to enter the MUC.
     * @return A {@link MucCreateConfigFormHandle} if the room was created while joining, or {@code null} if the room was just joined.
     * @throws XMPPErrorException if the room couldn't be created for some reason (e.g. 405 error if
     *         the user is not allowed to create the room)
     * @throws NoResponseException if there was no response from the server.
