Jackson module auto-discovery sets Jaxb Annotation Introspector as primary

[kincajou]

Hello.

Initially, when creating Jackson' ObjectMapper for Jersey needs, annotation introspectors order is defined - Jackson annotations first, JAXB annotations second (org.glassfish.jersey.jackson.internal.jackson.jaxrs.json.JacksonJaxbJsonProvider#DEFAULT_ANNOTATIONS).

31bd872 introduced module auto-discovery. If we have JAXB module in class path, when it is discovered and registered, it pushes JAXB annotation introspector back to primary (that's the default behavior of the module), thus breaking intended logic.

It looks like a bug, but maybe I'm missing something? Some configuration options?

It really hurts in DTOs with mixed annotations(jaxb ones are used for legacy xml endpoints).
ex.

public class Dto {
  @XmlElement(name = "jaxb")
  @JsonProperty("jackson")
  public String field;
}

response for Dto("abc") is {"jackson": "abc"} for v. 2.30.1, but for v. 2.32 it's {"jaxb": "abc"}
