You should still run on top of jdk11 or else you'll be missing security and performance enhancements. Openjdk is free and the same as the Oracle one, but without paid support.

You can get free builds of the OpenJDK source via Zulu (from Azul), AdoptOpenJDK, etc
It's only Oracle's build of that source that is no longer free
I've been using Zulu for years since its friendly licensing means you can easily incorporate it into your product (as part of a container image, for instance)

You can also get them directly from Oracle. https://jdk.java.net Follow the JDK11 link on the page, and that’s the open source, GNU licensed version. They then provide links to closed-source, commercially licensed versions

@Ming A Qi i’m afraid there’s a confusion between the JDK - the platform, and java - the language you still need a JDK if you want to write kotlin

yes, I get it. I just want to use the new language(for me) to do something. so i cared the jdk if is free
