I suspect the leak is in the application code rather than the rabbit 
java client libs.

I suggest you try removing *all* application code from the receive loop, 
leaving it looking like this:

while (runInfinite) {
         QueueingConsumer.Delivery delivery = consumer.nextDelivery();
         byte[] body = delivery.getBody();
         channel.basicAck(delivery.getEnvelope().getDeliveryTag(), false);
}

Let us know whether you still see a leak with that.

Regards,

Matthias.
