I have been running a vanilla Minecraft server for a while on a Raspberry Pi 4 with 4GB RAM. It actually runs great with my whole family on at the same time. I thought I would try turning it into a forge server but it WILL NOT RUN. This is all I get... root@ubuntu:/opt/minecraft# java -jar -Xms1G -Xmx3G forge-1.14.4-28.1.0.jar nogui [19:08:07] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, .,

Java isn't supporting Arm that I can find so OpenJDK is the only option. 1) Am I doing something wrong or is this just not going to run on OpenJDK? 2) I am still running Forge Clients with minimap and Optifine which don't seem to have a problem connecting and working on the vanilla server. What advantage is there to forge server?
