OK, so I was looking at the logs on the java side, it appears to be a
problem there, when I first add the route, the following shows up in

This appears to be a bug in the c++ broker, which for push routes is
sending a session-attached rather than a session-attach. That violates
the 0-10 protocol.
I also tried to do a pull route from the java side and got a different
exception:

This on the face of it is an internal error in the java broker when
handling the QMF request from qpid-route. I don't know enough about the
code in question to say where the fault lies exactly. (Could it be a
virtual hosts issue for example?)
Any ideas? should I submit a bug?
Yes, please . Ideally two separate bugs for each of these issues.
