JsonNodePropertyAccessorfor reading JSON object propertiesJsonArrayNodeIndexAccessorfor array index accessJsonNodeWrapperConverterfor type conversion betweenJsonNodeWrapperandJsonNodeEmbeddedJsonMessageHeadersMessageMapperfor JSON message serialization with embedded headersI've prepared changes to deprecate other Jackson 2 classes and make 3 as the project default, but this involves several changes and discussion points. (I encountered an NPE in Jackson 3 logic that maybe needs to be fixed by the Jackson team, but I've implemented a workaround in our code.)
For this reason, I've kept it separate from the current Accessor PR and will address it in the upcoming PR.
