Issue launching server on mxlinux
Froggg opened this issue ยท 2 comments
Fresh install of mx19, specifically for running servers off of, came with java installed but its the latest version so sure, extract .zip, run install.sh, change the min/max ram to amounts within my limit (16GB total, set max to 12, shouldn't be an issue on 64bit linux right?) then upon running ServerStart.sh, I receive this

doesn't even print a log cause this is just straight error in launching the jar I think? My apologies in case I missed something or misformatted this, correct me if I have, but I couldn't find any similar issues, or a better way to format. Thank you in advance, y'all have an awesome dev team
came with java installed but its the latest version
This is your issue. Minecraft Forge for 1.12.2 can only run on Java 8 due to changes in reflection changing how private class members are accessed.
Forge for 1.14+ will run on later Java versions as some future proofing has taken place, but last I checked this isn't officially supported as Minecraft itself still targets Java 8.
