Description

When autoDiscoverObjectMapper is set on JsonDataFormat definition, it is not propagated to JacksonDataFormat. Looking at the code in JsonDataFormatReifier I was not able to see this property in the list of populated properties.

 

Please see attachment for the reproducer project. ObjectMapperTest demonstrates the issue. In the route builder we set:

json.setAutoDiscoverObjectMapper("true"); 

but it has no affect, indicated by an exception on Java Time deserialization and a message in logs:

o.a.c.c.jackson.JacksonDataFormat        : The option autoDiscoverObjectMapper is set to false, Camel won't search in the registry
...
Exhausted after delivery attempt: 1 caught: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDate` (no Creators, like default construct, exist): no String-argument constructor/factory method to deserialize from String value ('2077-01-01')
