      Description

      I have a very simple route:

      class UiaRouteConfig extends RouteBuilder {
          @Override
          public void configure() {
              from("netty-http:http://0.0.0.0:8080/authorization")
                      .to("mock:foo");
          }
      }
      

      If I send a post with no data like this, it works as expected:

      curl -v -X POST http://localhost:8080/authorization
      

      However, if I send even one byte of data like this

      curl -v -X POST http://localhost:8080/authorization -d x
      

      netty throws this exception:

      If it helps, I have uploaded the two classes in this example, along with a maven pom file to build an executable .jar.
