Description
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'.
