@Provider @Consumes("*/*") @Produces({"application/json","text/json","*/*"}) public class CamundaJacksonJsonProvider extends tools.jackson.jakarta.rs.json.JacksonJsonProvider
Camunda variant of the Jackson 3 Jakarta-RS JSON provider that restores the empty-body handling the engine-rest resources rely on.

Background: for requests without an entity body, RESTEasy passes a null InputStream to MessageBodyReader#readFrom. Jackson 3's ProviderBase#_createParser forwards that stream straight to ObjectReader.createParser(InputStream), which rejects a null argument with an IllegalArgumentException ("argument \"src\" is null"). That surfaces to the client as an HTTP 500 instead of the graceful null entity the Jackson 2 provider produced.

By returning null from _createParser when the stream is null, the surrounding readFrom logic takes its empty-input branch. With JakartaRSFeature.ALLOW_EMPTY_INPUT enabled by default, this yields a null entity — exactly the Jackson 2 behaviour the engine-rest resources (e.g. redeploy, set job retries) expect when no request body is provided.
