Table openfire.ofConparticipant doesn't exist

Hi, all

My openfire is 3.8.1, I find some error in my log:

2015.05.05 11:22:29 org.jivesoftware.openfire.archive.ConversationManager - Table ‘openfire.ofConparticipant’ doesn’t exist

But actually, I find there is a table ofConParticipant in my mysql database, is it a bug or I need to upgrade openfire? Thank you!

after search, this is an old problem

Error in sql delete statement in monitoring plugin

but check the changlog, seem have not any record about that. Does any one know that?
