This simple plugin tries to repair IQ packets which have no 'id' attribute. According to RFC 3920 (Page 51) an 'id' attribute is required for IQ stanzas. Openfire 3.6.0a has an bug associated with this fact, which causes client disconnects. This problem is discussed here.
If an packet has no 'id' attribute this plugin does modify the packet by simply adding an 12-digit random 'id'.
Be aware that I have tested this not much!
