Exception in thread "Thread-29" java.lang.IllegalArgumentException: Group with name LiveJournal alread exists

On the similar note as http://www.igniterealtime.org/community/message/164173#164173 – is this my bad configuration, bad IcedTea, or bad openfire? Group LiveJournal is automatically created in my livejournal XMPP account, which is part of my openfire account through xmpp transport.
