> Key: CAMEL-18548
> URL: https://issues.apache.org/jira/browse/CAMEL-18548
> Project: Camel
> Issue Type: Improvement
> Components: camel-cxfrs, camel-jsonpath
> Affects Versions: 2.19.0
> Reporter: Nicolas Filotto
> Assignee: Nicolas Filotto
> Priority: Minor
> Fix For: 3.18.3, 3.20.0

> Since CAMEL-10646, a List is no more converted into an InpuStream by the
> JsonPathEngine but is directly treated as a List.
> This behavior change causes regressions on routes of the following 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 now treated directly as a List instead of being
> converted into an InpuStream like before which causes an error of the
> following 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'.}}
