Hiya 👋 I noticed something conflicting in the Kotlin documentation as well as some unexpected behavior when running Kotlin JVM Daemon via Gradle. Wanted to come here and ask what's the best way to go about contributing to the documentation of current behavior (and maybe a bugfix, we'll see)

The documentation on Kotlin JVM args has a few different parts

1. Gradle daemon arguments inheritance

If nothing is specified, the Kotlin daemon inherits arguments from the Gradle daemon. For example, in the gradle.properties file:

org.gradle.jvmargs=-Xmx1500m -Xms500m

2. Kotlin daemon's behavior with JVM arguments

If the Xmx argument is not specified, the Kotlin daemon will inherit it from the Gradle daemon.

🧵 for more details

First in VisualVM I can inspect the Gradle Daemon and I see everything I've set like Xmx, Xms, G1GC, Metaspace, CodeCache...

And for Kotlin Daemon Xmx and CodeCache are carried over, nothing else. This conflicts with both points in the documentation because:
• The first implies all Gradle JVM args would be carried over if nothing is supplied for Kotlin JVM args
• The second states only Xmx would be carried over, but nothing in the documentation mentions specifically pulling over ReservedCodeCache

When I do specify everything in kotlin.daemon.jvmargs everything is carried over as expected

My first goal would be to update the Kotlin Lang docs to point out this behavior clearly. My second would be - was it intentional to carry over ReservedCodeCache? I'd like to figure out where in Gradle or KGP that reference is and the reasoning behind that decision.

But I can't find the Kotlin Lang website source on GitHub so I'm not sure where to begin.

Okay nevermind, found it here https://github.com/JetBrains/kotlin-web-site/blob/master/docs/topics/gradle/gradle-compilation-and-caches.md
