I just did a fresh install of the 1.1 server and I seem to be getting the following error when running the recommended launch command.

Output of java -version:

java -version java version "1.8.0_311" Java(TM) SE Runtime Environment (build 1.8.0_311-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.311-b11, mixed mode)

As said this is a fresh install, no other mods added. Anyone an idea on how to fix it?

As per https://bugs.mojang.com/browse/MC-148234, it works correctly when changing the launch command to have all the parameters before the -jar forge-1.16.5-36.2.8.jar.
