Your version of Java is too modern; this version of Minecraft Forge requires you use Java 8, which has no concept of modules.

Either uninstall this latest version of Java and install a 64-bit build of Java 8, or should you require the latest version of Java for other purposes you can install Java 8 alongside it and then modify the start script so that it uses this version by absolute path, an example of this is as follows (which you can copy and paste assuming the installation location matches):-

@echo off

call settings.bat

:start_server
echo Starting Server
"C:\Program Files\Java\jre-1.8\bin\java.exe" -Xms%MIN_RAM% -Xmx%MAX_RAM% %JAVA_PARAMETERS% -jar %SERVER_JAR% nogui
pause
exit /B

goto start_server
