    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.

    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

    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)

    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.
