---------------------------------------
Summary: MessageContentsList no more converted into an InputStream
by JsonPathEngine causes regressions
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
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'.}}
