File transfers - where is it in openfire code?

DefaultFileTransferManager, but, naturally, I found that commenting out all that code from interceptPacket made no difference to the outcome of a ibb file transfer between two Spark clients.

I might add that I have disabled proxy transfers in the server settings.

So… My question is; where is the action taking place in the code? Doing a master on the subject, and not too much time left to find out about this.

I have been trying to find out where in band file transfers are handled in the openfire(3.6.0) code. I have been looking into MetaFileTransferInterceptor in
