Openfire does not include MUC status code 110 after joining a room and sending "self-presence" to the new occupant.
As shown in the last stanza, the "self-presence" sent by the room to the new user MUST include a status code of 110 so that the user knows this presence refers to itself as an occupant. This self-presence MUST NOT be sent to the new occupant until the room has sent the presence of all other occupants to the new occupant; this enables the new occupant to know when it has finished receiving the room roster.
