And vice versa. As someone who likes both languages, I appreciate how they both have their pros and cons. I was a Schemer before I learnt Java (when Java barely existed) and I adore Clojure, but if I were to write 10 MLOC mobile network routing and billing system, an air-traffic control system, or a credit-card transaction processing system etc. etc. that needs to evolve by a large team for 20 years, I would choose Java over Clojure any day. So I came to Java from C, C++, Scheme, and ML, and it's completely unsurprising to me why there has never existed a language that better supports large, long-lasting, important software (I'm not saying such a language couldn't exist, but it currently doesn't). And it's not just about the features Java has and, just as importantly, doesn't have (and if you think keeping features out of a programming language is easy, think again), but also how its evolution is handled.
In this particular case, of course it is more straightforward to embed what is effectively an untyped language in another untyped language than in a typed language, at least while keeping the language simple and without adding features we don't wish to add (even in TypeScript, working with JSON directly requires bypassing type checks). Still, as the JEP says, there are good, popular Java libraries that offer more convenient and powerful ways of working with JSON, but that is not the purpose of this particular package.
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."
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).
Ironically as a Clojure developer I would really love a JDK native JSON library that we could wrap to avoid having to ship 3rd party JSON deps. Sort of like how java.net.http made things simpler.
