[Java]OpenJDK OpenJ9

Solved

Hello I've just updated from 1.16.2 to 1.16.3 but I've found out that it constantly crashes (I'm using OpenJ9 for performance) but then I've the thought to change the JVM I'm using to the default Oracle Hotspot and it works (albeit quite inevitable lags due to hotspot being slow). Does that mean that OpenJ9 will not work anymore? I'm using Java 14 OpenJ9 which really gives me atleast 125FPS while the Oracle Hotspot gives only 50FPS and 1.5x the RAM.

I've seen problems related to using openjdk. Switching to Oracle jre usually solved them.

I don't play Minecraft but you can try to use ZGC for higher FPS if you are using OpenJDK/OracleJDK:

Java 14: java -XX:+UnlockExperimentalVMOptions -XX:+UseZGC

Java 15: java -XX:+UseZGC
