Minecraft Forums

Distro: Linux Mint 18.2

DE: Cinnamon 3.4.6

Java Version: openjdk-8-jre (8u131-b11-2ubuntu1.16.04.3)

I know for a fact Minecraft will run on this computer because it has done it before, but it has never done this.

Every time I open the launcher, it opens. The problem is that Minecraft will crash the minute I press play. No crash report exists, nor does the folder exist. I have tried deleting the .minecraft folder and restarting the installation, but to no ado. I have tried reinstalling the package, and also reinstalling openjdk-8-jre. Neither has worked.

I decided to run the minecraft-launcher through terminal, and this is the only output I could find that was worth mentioning:

Unrecognized VM option 'CMSIncrementalMode'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
[0819/114329:INFO:GameCallbacks.cpp(178)] launcher/launcher (main) info Process closed with exit code 256

What do I do?

I figured out the problem.

Minecraft was using my development kit of java 9.

All I did was uninstall java 9 for the time being, and reinstalled java 8.

And tada! It works!

sudo apt remove openjdk-9*
sudo apt remove openjdk-8*
sudo apt install openjdk-8-jre

Relaunch Minecraft and you are good to go.

@VentheDragon well, Do Minecraft not support for Java 9 (or Java 9 not support for Minecraft)? I have the same situationon on Win 7 with Java 9, and cannot find anything about that.

Minecraft is supported by Java 8 as far as I know, and not Java 9.
You can install Java 8 side-by-side with Java 9 and still run minecraft. Just enable Advance options in the menu and then set a custom Java path to the correct version (8). I however, was too lazy to do this as it requires a little bit more effort on Linux.

Ven, I am surprised that you seem content with openjdk. Oracle Java works significantly better on Linux for minecraft than openjdk. There are a couple ways to easily install Oracle Java 8.

by PPA (it updates itself):

manually (you update it regularly):

I have since switched to Fedora, but thanks for the info anyway.

I have already installed Oracle Java on Fedora, so I have noticed a slight improvement.
