So, if two beans involved in the tx use different proxy types (say unified and pooled), the chosen server won't be the same.  There's no real good way around this, since use of different proxy types implies different invokers on the server side, and hence different sets of targets.

As far as 4.2 is concerned, JRMP/Pooled and Unified invokers exist although the default ones are Unified. JRMP/Pooled are legacy so is there any reason why customers would want to use these? I'd expect for Unified to be at least as good as JRMP/Pooled, but I can see customers wanting to stick their environment to what it was like in 4.0.x, i.e. having as less changes as possible.

I haven't checked the trunk codebase, but the descriptors in trunk don't even show the JRMP/Pooled invokers.

To sum up, +1 on fine print :)
