The API you're using is the 0-10 protocol level API. It's really just 
there to implement JMS over AMQP 0-10. It's not something we recommend 
for general use as it is based directly on the 0-10 version of the 
protocol and can't be used with AMQP 1-0.

The Messaging API available in C++ and Python would support this use 
case as follows (this is presented in python for brevity):

   from qpid.messaging import *
   conn = Connection.establish("localhost")
   ssn = conn.session()
   replies = ssn.receiver("#replies; {create: always}")
   snd = ssn.sender("...")

   request = Message(reply_to=replies.source, content=...)
   reply = replies.fetch()

Unfortunately the Messaging API isn't yet available for Java. So you'll 
either need to code a blocking fetch on top of the lower level 0-10 API 
or use JMS.
