We need IIOP for JTS support (we use the same jars for JTA and JTS so we 
need it regardless of whether you enable JTS) .

We need  hornetq to leverage their fast journal (for our transaction logs).

I agree that Naryana compensations should not be required by the 
subsystem and this seems to be bringing in the bulk of the extra 
dependencies. I will look into why we need to include it in the subsystem.

Do you have more examples or do you agree that if we addressed the need 
for compensations in the subsystem then that would be good enough.
