The check is currently done in the `<clinit>` methods of `PlatformImpl` and `LauncherImpl` by calling the deprecated `System::getSecurityManager` method.

I also added a call to `checkSecurityManager` in `ReflectUtil` and `MethodUtil` in `javafx.base` for non-graphical applications that only use `javafx.base`.
