People who use Spring and Kotlin...
I've just recently implemented Google Pub/Sub with Avro serialization using Avro4k library and it works fine https://github.com/avro-kotlin/avro4k

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

Strings, Please! Eliminating Data Leaks Caused by Kotlin Assertions
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.

How Cloudflare security responded to log4j2 vulnerability
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.

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