Ok so I'm going to add other similar tests to check the rest of Brian's points. I don't want to use CPSCFJChannelFactory in the tests because it's a test-related object and I'd rather test the real thing. I could make DefaultClusteredPostOffice.syncChannel and asyncChannel fields protected, derive a test class from it exposing those fields and then use that class, but it looks like a lot of work for little payoff.
