Forge 1.15.2-30.1.0 crashes when started

[Duniau]

Hi

I am not expert at all in Linux - Plus I am not expert in Minecraft (my son plays on Playstation but he wants to use Mods and asked me to install the Linux version of the game to do so)

Minecraft is installed and works fine after I upgraded Java to the version 8

The version of Minecraft we have installed is 1.15.2 which corresponds to the Forge version we downloaded

Forge Installer works fine and the new "Forge" option appears besides the "last version"

Whenever we try to launch the game under the "Forge" option we get the following error message: "the game crashed whilst initializing  game / Error: java.lang.ExceptionInInitializerError: null"

I copy the log below my signature

Thank you very much for any help you may provide

JM

Thank you for your reply. I did a bit a research to understand what is OpenjDK and what is Openj9. My understanding is that these are two version of Java. I must say that I do not really know why one has been installed instead of the other. I had to upgrade java to java 8 to make Minecraft work but I may have installed J9 instead.

 

Would you have an advice about what I should do practically to shift from Openj9 to OpenjDK?

 

Best regards

JM

When we say OpenJ9 we don't mean OpenJDK 9.

 

To clarify there are two Java JVMs(the bit that actually reads and executes the Java bytecode) in the market right now:

• HotSpot, made by the OpenJDK community, and
• OpenJ9, made by IBM

Both are implementations of the Java JVM Specification, and as long as you use Java correctly any code you write should work on both.

However, Forge does not stay within the lines. Forge leverages implementation-specific and internal utilities of HotSpot to do its black magic, meaning it won't work on OpenJ9 that is different internally.

Hi, I thank you both for your help. The diagnosis was right. Forge needed OpenJDK to work. Some people explained that I just had to get OpenJDK from the package manager in Mint, which I did (I just discovered the use of this package manager). Then I found a tutorial on the web who explained how to switch from OpenJ9 to OpenJDK (using sudo update alternatives --config java) - I think it did not uninstall OpenJ9 (this was too complicated for me) but at least it allowed me to put openJDK forward and now Forge works. I guess I still have a learning curve on Linux
