Description

The rest-dsl doesn't support two post() endpoints with different request body types.

restConfiguration()
  .component("servlet")
  .contextPath("/api")
  .bindingMode(RestBindingMode.json)
;

rest("/user")
  .post("/employee").type(UserPojo.class)
      .route()
      .log("Name: ${body.name}")
      .endRest()
;

rest("/country")
  .post("/origin").type(CountryPojo.class)
      .route()
      .log("Name: ${body.country}")
      .endRest()
;

Both endpoints (/api/user/employee, /api/country/origin) tries to unmarshal the post body to CountryPojo and a JsonProcessingException is thrown when a UserPojo json is sent to /user/employee.
The problem is that they share one JascksonDataFormat instance registered with name "json-jackson" and the RestDefinition.type() sets the JascksonDataFormat.unmarshalType so at the end both post() endpoints will try to unmarshal to the same class.
