Forge 1.13.2 crashing on Linux only (Windows is fine) [SOLVED]

[CBWright]

I spent some time trying to figure this out last night, and made very little progress. I'm not sure what my next steps are, but I hope this information is useful to someone:

 

• 1.13.2-forge-25.0.146 crashes on two separate Linux machines, but runs just fine on my Windows machine. The most obvious difference between the two, other than Windows vs Linux, is that the Windows machine uses Oracle Java and the Linux machines use openjdk
• Here is a pastebin for the lastest log file: https://pastebin.com/Dr1V0QQZ
• No crash report is generated when this crash occurs (the last crash-reports file I have in my directory has a timestamp of 2019-04-06)
• This current log file is for a machine that has plugins loaded in it, but on my other Linux machine I deleted all my plugins and still got a crash.
• I can load vanilla 1.13.2 (no Forge) and it works fine
• Attempting to "back out" to a lower version of Forge still causes a crash. I suspect, though, that in that case I simply don't know how to clean up my minecraft environment properly.
• This is an observation only (so perhaps unreliable), but when I first installed .146 and fired it up in the launcher, it started downloading the extra files it needed, and the window closed before the progress bar indicated it was finished. A few seconds later the crash dialog came up. Ever since then, the crash dialog appears almost immediately after I click the launch button. So I wondered if perhaps it hadn't finished downloading the extra components it needs? Not sure how to verify that, though. If there's a way to get that information to you I'm happy to do so, I just need someone to tell me how.

Issue solved

It's because Forge doesn't support newer versions of Java. I suspect you probably have OpenJDK 11 or OpenJDK 12. You'll have to download an older Java runtime, then point Foge to it.

 

I had luck with the files here: https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

 

Get the Linux x64 tar.gz file and extract it somewhere. Then go to the profile settings for Forge and change the Java executable to the older one. I think you need to enable advanced settings.

Yep, that was the problem! I had both OpenJDK 11 and 8 installed on my machine. In the past Minecraft always defaulted to using 8 so I never really thought about it.

 

I removed 11 and Minecraft with Forge runs fine. So now that I know that, when I get home I'll take treebranch's advice, to into the settings on my other machine, and configure minecraft to use the v8 executable, see how that goes.

Is there a way to close/mark a thread as resolved? I was finally able to confirm last night that, as per treebranch's suggestion, I could simply configure each individual entry in the minecraft launcher to point to the openjdk 8 executable in /usr/lib and it launched fine, even with openjdk 11 installed as well. So this issue is now completely and thoroughly a non-issue. ?

 

Thanks all.

Best way is to just edit the thread title and put [SOLVED] at the beginning.
