Thank you Rob for the answer. Yes it really helps! I noticed that addresses in the form <exchange-name>/<routing-key> are also used with AMQP 1-0. Is it expected?

The Java Broker already makes some allowance for this with the notion of "globalAddressDomains" which you can set on the virtual host. For any domain <foo> in the list of defined globalAddressDomains, the virtualhost will accept messages sent <foo>/M as if it were sent to M (and the same with consuming). Also note that for the Java Broker an address of the form <exchange name>/<routing key> can be used to send / receive via AMQP 0-x exchange/routing-key semantics.
