title: camel http component is not set the response in the exchange body
body: <p>I am using Camel version 3.2.0 and Spring Boot Version 2.2.6.RELEASE .</p>
  
  <p>I am using camel-http component to consume a rest service which return list of product in JSON format.<br>
  I am trying to store in csv file.  Because of http response is not set in the out in exchange, the body is empty.</p>
  
  <p>I am using the below route.</p>
  
  <pre><code>&lt;route id="getProducts"&gt;
      &lt;from uri="quartz://groupName/timerName?cron=0 0/2 * 1/1 * ? *" /&gt;
      &lt;setHeader name="CamelHttpMethod"&gt;
        &lt;constant&gt;GET&lt;/constant&gt;
      &lt;/setHeader&gt;
      &lt;to uri="http://localhost:8080/product"&gt;&lt;/to&gt;
      &lt;log message=" before processor \n Body ${body} \n headers ${headers}"/&gt;
      &lt;!-- &lt;process ref="processor" /&gt; --&gt;
      &lt;log message=" before convert \n Body ${body} \n headers ${headers}"/&gt;
      &lt;marshal&gt;
          &lt;bindy type="Csv"  classType="com.basf.vo.Product"   /&gt;
      &lt;/marshal&gt;
      &lt;log message=" after convert \n Body ${body}"/&gt;
      &lt;to uri="file:\balachandar\?fileName=abc.csv"/&gt;
      &lt;log message="Products Received \n ============================= \n"/&gt;
  &lt;/route&gt;
  
  
  &lt;log message=" before processor \n Body ${body} \n headers ${headers}"/&gt; =&gt; It is printing Body {"productId":1,"name":"Pink Ralph Lauren Polo Shirt","category":"Dress"} in the console
  
  &lt;log message=" before convert \n Body ${body} \n headers ${headers}"/&gt;  =&gt; It is not printing the body. Body is empty.
  
  I used custom processor to know the body.
  
  public void process(Exchange exchange) throws Exception {
      String msg = exchange.getIn().getBody(String.class);
      String msg1 = exchange.getMessage(String.class);
      System.out.println("Rest Response is:-&gt;" + msg);   //  Rest Response is:-&gt;
      System.out.println("Rest Response is:-&gt;" + msg1);  //  Rest Response is:-&gt;null
  
  }
  </code></pre>
  
  <p>It is printing the body first time, but not subsequent time through processor or log component.<br>
  I am not sure why response is not set in the body.   Please help on this.</p>
