Issue with jackson library after upgrade to 2.19.0 as dependabot suggested

[juanroldan1989]

Hello,

Dependabot requested we upgrade to the latest Jackson library in one of our Java applications:

    implementation "com.fasterxml.jackson.module:jackson-module-kotlin:2.19.+"
    implementation "com.fasterxml.jackson.core:jackson-core:2.19.+"
    implementation "com.fasterxml.jackson.core:jackson-databind:2.19.+"

But we had to roll it back because it was not working with Open API and the Actuator endpoint.

Therefore our application running in ECS was failing because the health-checks in our Target Groups pointing to the actuator endpoint was failing. The Java application itself was running fine, the actuator endpoint was failing with "No such method" error, which made it even harder to find out why our application was crashing.

Hopefully this is useful to anyone upgrading to the latest jackson library version.

@juanroldan1989 I've reported this to GitHub. I hope your Jackson 5 joke that you've edited was at least funny to you.

I've added a full description of the issue. I apologise for the joke, it was not funny, but the issue is real and it happens when upgrading to the latest version of the library, hopefully it will save someone else's a couple of hours of debugging.

Dockerfile for our Java application has base image: openjdk:18-jdk-alpine

Without having any other information than what is presented, I'd guess you have older (pre-2.19) version of jackson-annotations. So possibly just add:

implementation "com.fasterxml.jackson.core:jackson-annotations:2.19.+"

not sure why this would be needed, TBH, since jackson-databind depends on jackson-annotations -- most likely you are depending on something that has different version dependency. F.ex Spring/Quarkus provide their own defaults.

If possible, it'd probably make sense to depend on Jackson BOM (jackson-bom) versions 2.19.0 to get a consistent version set.
