Description

If a message sent to a headers exchange matches two bindings to one queue, it is enqueued to that queue twice.

Further, if the queue and the message are durable, journal raises error:

JERR_MAP_DUPLICATE: Attempted to insert record into map using duplicate key.

Reproducer:

qpid-config add queue MyQueue --durable
qpid-config bind amq.match MyQueue SomeKey any property1=value1
qpid-config bind amq.match MyQueue OtherKey all property2=value2
qpid-send -a "amq.match" -m 1 -P property1=value1 -P property2=value2 --durable=true
