I verified that the above addressing string can be specified in the
JNDI properties.
A word of caution, if you use say amq.match (the default headers
exchange instead of your own headers exchange) then make sure to put
it inside single quotes in the address string.
Ex my-subscription-queue; {create:always,
node:{x-declare:{auto-delete:True},
x-bindings:[{queue:my-subscription-queue, exchange:'amq.match',
arguments:{'x-match':all,a:b,c:d}}]}}
