If a maximum redelivery count is specified for a queue on the broker and the message is prefetched to the consumer a number of times equal to the maximum number of redeliveries, it goes to the DLQ, if rejected. This was reproduced with a consumer in SY / JBoss EAP, with jms.redeliveryPolicy.maximumRedeliveries=0 specified on the failover URI and a maximum of 5 specified on the broker redeliveryPlugin.

Delivery to DLQ was instigated by failing the broker over a few times in relatively quick succession.
