Issue solved need to use --installserver as part of the starting args.
See https://github.com/MinecraftForge/Installer/blob/master/src/main/java/net/minecraftforge/installer/SimpleInstaller.java under OptionSpecBuilder, nogui is not an option and no option used will cause it to try and load a gui on a headless (no display/monitor) device/server.
