Jackson 2.19.0 issues #7036

manusa · 2025-04-25T13:21:58Z

          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:

  additionalProperties:

Also see this happening - breaks applying kubectl manifests we use.
( Got hit by that via dependabot automatically updating from 7.1.0 to 7.2.0 )

We also have the problem on the Apache NiFi project where we cannot bump Jackson to 2.19.0 because of this.

~~I'll try to see if a 7.2.1 with a patch is feasible and doesn't break anything.~~

#7038 is too breaking for a patch release. Considering a 7.3.0 with this single change.

wleese · 2025-05-28T13:52:08Z

Will this fix be backported to 6.x?

I saw Spring Boot 3.5.0 released with Jackson 2.19.0, and (perhaps releasing today) Spring Cloud 2025.0.0 uses fabric8 kubernetes client 6.x and is not planning on moving to 7.x. This puts Spring Boot + Spring Cloud users in a bit of a bind.

Given the Spring Cloud context, we might have to port it then.
Can you please create a specific issue for that so that we can track it?

Sure, here it is: #7106
