Sure, but as I showed in the post I didn't see the difference but I  
was probably
doing something wrong.

Well... Yes, it's just annoying because then I need to replicate this  
call in every
place where I need a durable exchange and it would be a lot easier if  
it was part
of the client api (I attached patches for the stuff that I needed in  
this ML, and I see
that part of the things are already there in the recent client  
revisions).

I don't really have java setup here (and I don't even know how to set  
it up to be honest,
I'm happy without knowing java) so it would take a considerable effort  
to do so... it's
definitely possible that it's an error on my side so I wouldn't worry.
