[Java problem]

You modified the jar file directly with something and didnt delete the META-INF folder in the jar. Causing this security issue to pop up. Please note that if you added a mod to the jar file, you did it incorrectly. There's very few things that need to be added to the modpack.jar file (aka forge universal file) directly anymore.
