Changing the code to this obtained the desired result:
SubscriptionManager idSubscription(session);
Message m;
LocalQueue lq;
qpid::sys::Duration duration(1000000000);
std::string queue("queue");
std::string unique = qpid::framing::Uuid(true).str();
idSubscription.subscribe(lq, queue,
SubscriptionSettings(FlowControl::messageCredit(1),
qpid::framing::message::ACCEPT_MODE_NONE,
qpid::framing::message::ACQUIRE_MODE_NOT_ACQUIRED, 0), unique);
lq.get(m, duration);
It appears that SubscriptionManager::get uses a separate SubscriptionSettings
and thus was not honoring the previous calls to configure the settings from the
SubscriptionManager::setAccetMode, etc.
