Interesting. I removed UNICAST from my TCP stack for a while now and did not see any regression (though I've seen some mystical differences). I see some statements supporting that: (http://www.jgroups.org/newuser/node67.html) "Since TCP already offers some of the reliability guarantees that UDP doesn't, some protocols (e.g. FRAG and UNICAST) are not needed on top of TCP."
So, just to be sure, I'll ask JGroups list why UNICAST is used in the example TCP configurations.

It seems useless to have rebuild a reliable unicast on top of TCP but there might be some other undocumented side effect.
