Description

Camel Tracing is not being executed if there is redelivery strategy defined.
In our context we have switched on the camel Tracer with the following:

    public static void main(String[] args) throws Exception {
        DefaultCamelContext context = new DefaultCamelContext();
        context.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {

                // If errorHandler with redelivery is removed then tracer output is visible again.
                errorHandler(new DefaultErrorHandlerBuilder().maximumRedeliveries(3).redeliveryDelay(2000L));

                from("direct:start").process(new Processor() {
                    public void process(Exchange exchange) throws Exception {
                        System.out.println("PROCESSED");
                    }
                });
            }
        });

        // Enable Tracer.
        context.setTracing(true);
        context.start();
        ProducerTemplate template = context.createProducerTemplate();
        template.sendBody("direct:start", "foo");
    }

We noticed that we were missing output from the tracer that we were excepting.
If you remove the errohandler with redelivery you can see the output we expected:

 

[main] INFO org.apache.camel.processor.interceptor.Tracer - ID-rmm-xxx-xxx-x-x >>> (route1) from(direct://start) --> Processor@0x130d63be <<< Pattern:InOnly, Headers:{breadcrumbId=ID-rmm-xxx-xxx-x-x}, BodyType:String, Body:foo
