Description

When we use the component trying to unmarshal such as in the following route:

    public void configure() throws Exception {
       from("direct:unmarshal").unmarshal().json(JsonLibrary.Jackson, User.class).to("direct:logger");
        ...
    }

    static class User {...}

The following piece of code is returning null due to missing class in the classloader: https://github.com/apache/camel/blob/main/components/camel-jackson/src/main/java/org/apache/camel/component/jackson/AbstractJacksonDataFormat.java#L512

This is happening when you have routes dynamically loaded such as in the case of camel-k.
