Not able to access any of those solace specific headers,

    @StreamListener("solace-test")
    public void onMessage(Message<String> message){
        Destination destination = message.getHeaders().get(SolaceHeaders.DESTINATION, Destination.class);
        System.out.println("DESTINATION :: " + destination.getName());
        System.out.println("MESSAGE " + message.getPayload());

        System.out.println("solace_correlationId " + message.getHeaders().get("solace_correlationId"));
        System.out.println("solace_destination " + message.getHeaders().get("solace_destination"));
        message.getHeaders().forEach((k,v)-> {
            System.out.println("KEY :: " + k + " Value " + v );
        });
    }

Also another question is does solace scs use JMSXDeliveryCount internally for any purpose?
