Unfortunately that library requires paying tribute to its owners, only made relevant thanks to shipping in phones powered by a green droid.

"The next thing is also fairly straightforward: we expect Kotlin to drive the sales of IntelliJ IDEA. We’re working on a new language, but we do not plan to replace the entire ecosystem of libraries that have been built for the JVM. So you’re likely to keep using Spring and Hibernate, or other similar frameworks, in your projects built with Kotlin. And while the development tools for Kotlin itself are going to be free and open-source, the support for the enterprise development frameworks and tools will remain part of IntelliJ IDEA Ultimate, the commercial version of the IDE. And of course the framework support will be fully integrated with Kotlin."

Isn’t json processing still a dependency in Kotlin? I love the language but I don’t think it’s equivalent to built in json processing.

I'm pretty partial to Groovy's JSON library - it has a nice syntax it just works (caveat that I had issues once where the size of the JSON was multiple megabytes and it corrupted).
