XML Support and Class Shading in jersey-media-json-jackson

[WannabeSoftwareEngineer]

Hi,
in our project, we’re currently using org.glassfish.jersey.media:jersey-media-json-jackson to provide support for JSON serialization, which works great.
Now we’re looking to add support for XML-based endpoints, but we’ve run into a bit of a roadblock and could use some guidance.

As far as we know, there isn’t a direct XML equivalent of jersey-media-json-jackson.
Since jackson-jaxrs-providers offers XML support, we thought we would write a JAX-RS feature using its XML provider, but this has led to having to deal with core classes being duplicated. The core classes are coming both from the shaded version in jersey-media-json-jackson and the regular jackson-jaxrs-providers xml module, like, for example, JacksonFeatures.java.

To avoid the complexity of managing duplicated classes, we’re considering rewriting our JSON feature to use the JSON provider from jackson-jaxrs-providers directly, simplifying the setup.

My questions would be:

• are updates to jackson-jaxrs-providers typically backported to jersey-media-json-jackson?
• could you provide some context around why the classes were shaded in jersey-media-json-jackson? Maybe there is something that we are overlooking.

Appreciate any insights.
Thank you.
