Taitan-

I was playing a forge server with some friends yesterday, but today I added some mods and suddenly the server wouldn't star, then I realized that the optifine was the problem. Now the server starts but my friends can't join, and this message appears on the cmd WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by cpw.mods.modlauncher.SecureJarHandler (file:/C:/Users/Nicolas/Desktop/Server%20Tationland/libraries/cpw/mods/modlauncher/8.0.9/modlauncher-8.0.9.jar) to field java.util.jar.Manifest.jv WARNING: Please consider reporting this to the maintainers of cpw.mods.modlauncher.SecureJarHandler WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release Can someone help me?
