Review Request: JDK-8165563 ClassLoader::getSystemClassLoader will never be null

[Patrick Reinhart]

Hi Mandy

Found a tiny typo ony line 1453, that could also be fixed with this change:

1451      * @throws  IOException
1452      *          If I/O errors occur
1453 
1454      * @since  1.2
1455      */
1456     public static Enumeration<URL> getSystemResources(String name)

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.
