  strictNullCheck option in the Kotlin module doesn't cover non-object-field situations at all. https://github.com/FasterXML/jackson-module-kotlin/issues/479

  But, it sucked. I was constantly finding bugs related to nullability, around generics, inline/value classes, etc. And it wasn't the typical trivial ones, either. Figuring out that you're calling a Java library and encountering a "platform type" is the least problematic. My biggest struggle came from using libraries that were written in Java first, but then added a Kotlin API on top. So, my code didn't know I was dealing with a platform type and neither did I. Yet they were still broken. Some of them are broken in an unfixable way, such as JacksonXML's Kotlin module: https://github.com/FasterXML/jackson-module-kotlin/issues/479. So many Java libraries rely on reflection even when it's not obvious that they might, so you pretty much can't ever use value classes in Kotlin, including the unsigned number types.

• From Java to Kotlin. There and back again

  You should add Jackson Module Kotlin in your project. After that, you can't specify a type of object explicitly.

  Not really, you just need to handle some standard types and have a good extension mechanism to let the user implement factories. That library having built in support for UUID and datetime is probably a bit much, I'd prefer a plugin like https://github.com/FasterXML/jackson-module-kotlin

• Ktor vs Spring for creating an API

  There is a bug at this very moment that makes it literally impossible to deserialize [1, 2, 3, null] into a List with Jackson's Kotlin module. Yes- even if you set KotlinModule(strictNullChecks = true). It's just broken. (Here's the link: https://github.com/FasterXML/jackson-module-kotlin/issues/479)

• Kotlin Team AMA #3: Ask Us Anything

  Got you, thanks. I didn’t mean to sound offensive - a better wording would be that they don’t seem to prioritize this part, at least based on https://github.com/FasterXML/jackson-module-kotlin/issues/199, which has one abandoned branch from a 3rd party and a couple of comments from from maintainers.

• kotlinx.serialization 1.2 Released: High-Speed JSON Handling, Value Class Support, Overhauled Docs, and more
  5 projects | /r/Kotlin | 7 May 2021

  If you use Jackson, don't forget to include the Kotlin extensions https://github.com/FasterXML/jackson-module-kotlin

• Serializing and deserializing "Any" Kotlin type using jackson mapper

  Did you include jackson-module-kotlin?
