Open fire sends Unsubscribe instead of unsubscribed when user deny the subscription from other side

Hi Admin

We are using open fire for our federation system, currently we found that the openfire is not behaving as per RFC,

Open fire is sending the UNSUBSCRIBE instead of UNSUBSCRIBED ,when open fire user deny the coming subscription from other end.

I can see the version mentioned in the openfire.sh file is:

$RCSfile$

$Revision: 1194 $

$Date: 2005-03-30 13:39:54 -0300 (Wed, 30 Mar 2005) $

Kindly provide your suggestion on this. whether this is already resolved in latest release or still to cater.

Regards,
