@JsonFormat does not work with Graalvm + quarkus-resteasy-reactive-jackson

See original GitHub issue

Describe the bug

I have a data class with a OffsetDateTime.

data class MyData( @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd'T'HH:mm:ssZ", timezone = "UTC") val myTime: OffsetDateTime) When running under Java the serialization works, in native mode it doesn’t.

Expected behavior

{ "myTime": "2021-03-10T19:15:00+0000" }

Actual behavior

{ "myTime": 1615403700.000000000 } Environment (please complete the following information):

GraalVM version: 21.0.0
Quarkus version or git rev: 1.12.2.Final
Build tool (ie. output of mvnw --version or gradlew --version): Gradle 6.6.1

Maybe here? https://quarkus.io/guides/rest-json#jackson .

Currently there is no Kotlin in those guides, but if we do add Kotlin examples at some point, we will certainly consider this.

But I still think this is a bug. Isn’t it possible to get it to work?

There is nothing Quarkus can do about this. It has to do with the bytecode Kotlin produces and how Jackson handles the annotation lookups

But I still think this is a bug. Isn’t it possible to get it to work? We are using the annotation in multiple quarkus and spring projects and it works everywhere without the the field specifier.
