[rabbitmq-discuss] Trouble with confirms

If i enable confirms , then:
"The broker will confirm messages once:
* it decides a message will not be routed to queues (if the mandatory
flag is set then the basic.return is sent first) or
* a transient message has reached all its queues (and mirrors) or
* a persistent message has reached all its queues (and mirrors) and been
persisted to disk (and fsynced) or
* a persistent message has been consumed (and if necessary acknowledged)
from all its queues"
So, if i send a persistent message (delivery mode = 2) to a non-durable
exchange which routes to a non-durable queue, then i will only get a
confirmation once the message has been consumed from that queue, right?
And if my consumer is not set to auto-acknowledge, then i will only get
a confirmation once the consumer has acknowledged the message, right?
This does not seem to be happening for me. I get a confirmation 12
milliseconds after sending the message, but i know the acknowledgement
isn't being sent for another whole second. I can't tell if the
confirmation is being sent when the broker receives the message, gives
it to an exchange, puts it in a queue, or delivers it to a consumer,
since all those things happen in very rapid succession.
Any ideas as to what i should look into?
I'm using the Java API, if that matters.
