Gatling JMS on IBM MQ tries to access unauthorized queue (SYSTEM.DEFAULT.MODEL.QUEUE) - scala

Question

I have a problem running a Gatling JMS (IBM MQ) scenario on my test environment (which I don't have admin access).
The scenario works all fine on my own IBM queues running under docker on my own workstation.
According to the exception, it seems it tries to access queue SYSTEM.DEFAULT.MODEL.QUEUE to create a temporary queue (why does it even try to create a temporary queue in the first place?).
My scenario is a very basic requestReply one.
val MY_SCN = scenario("MY_SCN").repeat(1) {
exec(
jms("req MYSCN")
.requestReply
.queue("IN_QUEUE")
.trackerQueue("OUT_QUEUE")
.textMessage("Whatever message")
)
}
Here is my JMS factory setup:
val ff: JmsFactoryFactory = JmsFactoryFactory.getInstance(JmsConstants.WMQ_PROVIDER)
val cf: JmsConnectionFactory = ff.createConnectionFactory
cf.setStringProperty(CommonConstants.WMQ_HOST_NAME, MQ_HOST)
cf.setIntProperty(CommonConstants.WMQ_PORT, MQ_PORT)
cf.setStringProperty(CommonConstants.WMQ_CHANNEL, MQ_CHANNEL)
cf.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT)
cf.setStringProperty(CommonConstants.WMQ_QUEUE_MANAGER, MQ_QM)
cf.setStringProperty(CommonConstants.WMQ_APPLICATIONNAME, "JmsPutGet (JMS)")
cf.setBooleanProperty(JmsConstants.USER_AUTHENTICATION_MQCSP, true)
cf.setStringProperty(JmsConstants.USERID, MQ_USER)
cf.setStringProperty(JmsConstants.PASSWORD, MQ_PASSWORD)
Here is my JMS config
val jmsConfig = jms
.connectionFactory(cf)
.credentials(MQ_USER, MQ_PASSWORD)
.messageMatcher(...)
.usePersistentDeliveryMode
Here is the exception:

Thanks to #JoshMc for the hint.
Here is the fix:
val MY_SCN = scenario("MY_SCN").repeat(1) {
exec(
jms("req MYSCN")
.requestReply
.queue("IN_QUEUE")
.replyQueue("OUT_QUEUE")
.trackerQueue("OUT_QUEUE")
.textMessage("Whatever message")
)
}
