Thought I had answered this yesterday, but I don't see my reply. Yes, there appears to be some magic somewhere, but I can't find it. Must be in the launcher because the hotspot arguments.cpp only accepts the "=" from of the argument: 

    } else if (match_option(option, "--add-modules=", &tail)) {
      if (!create_numbered_module_property("jdk.module.addmods", tail, addmods_count++)) {
        return JNI_ENOMEM;
      }
