When using an OpenJDK implementation such as Eclipse Adoptium (used by default by most launchers), Xoroshiro128PlusPlus is not an available RandomGenerator algorithm. This algorithm is available via the full Oracle JDK, however.

While this may be a fairly minor issue, Minecraft can, and does, crash if multiple threads access the LegacyRandomSource

java.lang.IllegalStateException: Accessing LegacyRandomSource from multiple threads

While manually switching to the full Oracle JDK is an option, it may be better to switch to using and packaging something like Apache Commons RNG Core to ensure a proper RNG algorithm gets used, instead of relying on the fallback to the Mojang implementation.
