Shenandoah Crash in Minecraft

[Robin Kuiper]

Hi,

I attempted using the Shenandoah GC when running minecraft, but
encountered a reproducible crash during startup. 
Info:
OS: Arch Linux, latest updates
Java: 12.0.2.u10-1, from the official Arch repository
Minecraft Launcher version: 2.1.5965
Minecraft version: 1.14.4

Crash log: 
https://bugs.mojang.com/browse/MC-158532
https://bugs.mojang.com/secure/attachment/230803/hs_err_pid1036.log

Reproducing steps:
1: Download & install the launcher according to these instructions
2: Set up a new minecraft installation with the following settings:
	Version: 1.14.4
	Java executable: /usr/lib/jvm/java-12-openjdk/bin/java
	JVM Arguments: -Xmx2G -XX:+UnlockExperimentalVMOptions
-XX:+UseShenandoahGC
3: Press save & Start the installation

If this is not the correct location to report such a bug, apologies,
please point me in the right direction!

Have a nice day,
Robin
