OTG does this thing where a component of it is extracted to a 1.12.2 folder in your mods folder. The annoying thing about this is that component depends back on the code of the main part of the mod, so when you remove the main part of the mod that you can see, the extracted part in /mods/1.12.2/ that hasn't done anything to say "I'm in here!" crashes your game.

This error indicates you are running the server with Java 9 or later. Even if you had Java 8 installed and got this error it means that Java 8 installation is not the installation your PC is attempting to use. The fix for this is either remove all other Java installations, or Fully qualify the java invocation by specifying the full path to the java exe
