Openfire MUC destroy

I am having a bit of issues destroying a MUC room and having all participants notified:

I have tried:

<iqfrom='crone1@shakespeare.lit/desktop'
    id='begone'
    to='heath@chat.shakespeare.lit'
    type='set'>
  <queryxmlns='http://jabber.org/protocol/muc#owner'>
    <destroyjid='coven@chat.shakespeare.lit'>
      <reason>Macbeth doth come.</reason>
    </destroy>
  </query>
</iq>

and the room is destroyed fine, but no participants are notified of the destruction. I have been able to destroy the room fine with Openfire console and users are notified (ONLY when there is no alternative MUC room added, I tried it with a fake address and a real address and NEITHER worked).

I have also tried:

<iqfrom='crone1@shakespeare.lit/desktop'
    id='begone'
    to='heath@chat.shakespeare.lit'
    type='set'>
  <queryxmlns='http://jabber.org/protocol/muc#owner'>
    <destroy>
      <reason>Macbeth doth come.</reason>
    </destroy>
  </query>
</iq>

Which according to the XMPP Documentation SHOULD work but i receive a 500 internal server error. Is this a bug?

I am running: Openfire 3.7.2 Beta

Any help would be greatly appreciated!
