I had to install java 8 and switch to java 8 to start the forge server and then switch back to java 11 for my other things... It's quite the hassle as other applications that are critical rely on java 11. Would be nice if it would get updated to work with newer versions

I have done a new and fresh install of the forge server using the installer on my ubuntu 18.04 server. I just used the installer with the -installServer argument. It installed everything but whenever i run the server i get these exceptions daniele@daniele:~/forge$ java -Xmx1024M -Xms1024M -jar forge-1.14.4-28.0.45.jar nogui [19:56:10.658] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 28.0.45, --fml.mcpVersion, 20190719.225934, --fml.mcVersion, 1.14.4, --fml.forgeGroup, net.minecraftforge, nogui] [19:56:10.662] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 3.2.0+60+b86c1d4 starting: java version 11.0.4 by Ubuntu [19:56:10.881] [main/INFO] [ne.mi.fm.lo.FixSSL/CORE]: Added Lets Encrypt root certificates as additional trust [19:56:10.921] [main/WARN] [ne.mi.fm.lo.FMLConfig/CORE]: Configuration file /home/daniele/forge/config/fml.toml is not correct.

without any problems. I've tried to re-install forge many times, or used already pre-packaged modpacks but nothing seems to work. Also bear in mind i have not installed any plugins or mods just a fresh forge server install. Even the vanilla server that comes with forge starts and prompts me for the eula. but the forge server just keeps crashing. Even after eula acceptance.
