My setup:
Openfire nightly 2014-05-15 (I would like to test message carbons with the fix from CSH)
Jitsi 2.5.5218
Problem:
When connecting with Jitsi (both desktop client and mobile client) "nothing happens" in the client and the following error is show in the server error log:
2014.05.16 07:05:39 org.jivesoftware.openfire.nio.ConnectionHandler - Closing connection due to error while processing message: ...xml... The feature requested is not implemented by the recipient or server and therefore cannot be processed. ...xml...
Jitsi desktop and mobile clients have worked well in OP3.8.2, OF3.9.2 and OF3.9.3 (the versions we have been using).
