---------------------------------------

             Summary: MessageContentsList no more converted into an InputStream by JsonPathEngine causes regressions
                 Key: CAMEL-18547
                 URL: https://issues.apache.org/jira/browse/CAMEL-18547
             Project: Camel
          Issue Type: Improvement
          Components: camel-cxf, camel-jsonpath
    Affects Versions: 2.19.4
            Reporter: Nicolas Filotto
            Assignee: Nicolas Filotto
             Fix For: 3.18.3, 3.20.0


Since the addition CAMEL-10646, a List is no more converted into an InpuStream by the JsonPathEngine but directly treated as a List.

 

This behavior change causes regressions on route of type:

{{from("cxfrs://...").setBody().jsonpath("$.name")}}

where the related rest endpoint consumes json payload as next:

{{@Path("/customer")}}
{{@POST}}
{{@Consumes(\{ "application/json" })}}
{{@Produces(\{ "application/json" })}}
{{Object createCustomer(String payload);}}

The payload received is wrapped by the consumer endpoint into MessageContentsList which is not treated directly as a List instead of being converted into an InpuStream like before which causes an error of type:

 

{{org.apache.camel.ExpressionEvaluationException: com.jayway.jsonpath.PathNotFoundException: Expected to find an object with property ['name'] in path $ but found 'org.apache.cxf.message.MessageContentsList'. This is not a json object according to the JsonProvider: 'com.jayway.jsonpath.spi.json.JacksonJsonProvider'.}}
