Just FYI: We use Jackson in our K8s related projects and also got this update via Renovate today. We are using Gradle, so bumping Jackson in our dependencies will indirectly also bump it for the fabric8 client. I've seen two issues so far (just in case those are not covered by the existing tests).

NullPointerException

No further invesigation, but saw this stack trace in one of our update PRs:

CRD generation

With this Gradle build script the generated CRD has a ton of new additionalProperties:

getAdditionalProperties:
  additionalProperties:
    type: "object"
  type: "object"

The problem is in the UnmatchedFieldTypeModule, which replaces the BeanPropertyWriter instances for @JsonAnyGetter properties—which are of type AnyGetterWriter—with BeanPropertyWriterDelegate instances. I haven't checked the behaviour in 2.18.3, but in 2.19.0, some "primary context resolving" (in BeanSerializerBase, line 396) is then not called, as the writer is not of the expected class:

            if (prop instanceof AnyGetterWriter) {
                ((AnyGetterWriter) prop).resolve(provider);
            }

It would seem the delegate should (now?) inherit the AnyGetterWriter instead?

Edit: seems @r1c4r60 knows this well!
