> ClassLoader::getPlatformClassLoader [1] is added in JDK 9 that is parent or ancestor of the system class loader [1].  The system class loader will never be null.  Another relevant change in JDK 9 was that the system initialization was reworked that the built-in system class loader is initialized very early during startup.
