public JID getUserAddress() {
        return userJid;
    }
The JID of the user (the real JID, eg: 'user@domain/desktop`) that is the occupant of a room (as represented by
this instance); contrast with {@link #getOccupantJID()}.

A {@code null} null value is returned when this instance is a self-representation of the room.

@return The address of the user that joined the room or null if this instance represents to the room itself.
