>                 Key: CAMEL-19500
>                 URL: https://issues.apache.org/jira/browse/CAMEL-19500
>             Project: Camel
>          Issue Type: Bug
>          Components: camel-jetty, core
>    Affects Versions: 3.20.4
>         Environment: $ lsb_release -d
> Description:    Ubuntu 22.04.2 LTS
> $ java --version
> openjdk 19.0.1 2022-10-18
> OpenJDK Runtime Environment GraalVM CE 22.3.0 (build 19.0.1+10-jvmci-22.3-b08)
> OpenJDK 64-Bit Server VM GraalVM CE 22.3.0 (build 19.0.1+10-jvmci-22.3-b08, mixed mode, sharing) 
>            Reporter: Fyodor Kravchenko
>            Priority: Minor
>
> In Camel 2, when the form was submitted, the payload was able to be presented as a {{java.util.Map}} like this:
>  
> {code:java}
> Map map = httpMessage.getBody(Map.class);{code}
> In Camel 3.20.4 this doesn't work.
>  
> I've created a [little github project|https://github.com/fedd/cameljettyformmap/tree/main/cameljettyformmap] to demonstrate and reproduce the error. In the project's [{{pom.xml}}|https://github.com/fedd/cameljettyformmap/blob/main/cameljettyformmap/pom.xml] file you can easily switch the Camel versions to see how version 2.24.0 behaves as expected in a true Camel manner, and 3.20.4 does not.
> In essence, the code to check the behavior is like below. {{form.html}} is a simplest POST web form. 
> {code:java}
>                         HttpMessage http = exchange.getIn(HttpMessage.class);
>                         HttpServletRequest request = http.getRequest();
>                         String method = request.getMethod();
>                         if ("POST".equals(method) || "PUT".equals(method)) {
>                             Map map = http.getBody(Map.class);
>                             String string = http.getBody(String.class);
>                             http.setHeader(Exchange.CONTENT_TYPE, "text/plain");
>                             http.setBody("json: " + mapper.writeValueAsString(map) + ", and string:" + string);
>                         } else {
>                             http.setHeader(Exchange.CONTENT_TYPE, "text/html");
> http.setBody(this.getClass().getResourceAsStream("form.html"));
>                         } 
> {code}
> It should print the jsonified form POST payload, but doesn't for the Camel 3.
