List of JVM support for Faster Random's generator.

Known Working JVM's

_{These JVM's work perfectly with Faster Random on all versions that JEP 356 applies to.}

The version denoted only confirms if a JDK version is known to work on the latest non-headless version of that JDK.

JDK	Java 17	Java 21
GraalVM	✅	✅
OpenJDK	✅	✅
Microsoft JDK	✅	✅
Adoptium	✅	✅
Azul Zulu	✅	✅

Know a working/broken JDK? Comment what it is!

Headless JDK's tend to not bundle the random generators that Faster Random requires. Some variants of OpenJDK do not have this as well. If the LXM generators are not available, Faster Random will display a pop up, or silently crash.

For all of these JVM's I have actually downloaded them and physically created a world for each one. Are you sure you're not using a headless JDK? If you do, minecraft will still open, but stuff like RandomGenerator and JavaFX will crash the game.

I will note I'm using an x86_64 Linux build, so I'm not sure if that isn't supported on Windows.

I am indeed using Windows, x86_64 as well. I'll give it a shot on Linux, it might be that the ones built for Linux have different tunings from Adoptium.

Edit: Definitely not using a headless JVM. Afaik Graal doesn't even provide binaries for headless, though if they do I havent actively tried to install a headless version

Hello, I'm running Windows 11 24H2 x64 with GraalVM CE

Tried with Azul Zulu, same result.

Your JVM should support it, but this seems to be an issue with how loading works with the fork of PaperMC that you're using. Unless the issue also shows up with Faster Random on the latest fabric version (it won't crash, so you'll have to look for the warning in logs), this issue doesn't apply here.
