Default Package Is No Longer null

In Java 8 asking a class in the default package for its package returns null:

System.out.printf("Class : '%s'%n", ClassInDefaultPackageTest.class); System.out.printf("Package : '%s'%n", ClassInDefaultPackageTest.class.getPackage()); System.out.printf("Package name : '%s'%n", packageName());

Output on Java 8:

Class : 'class ClassInDefaultPackageTest' Package : 'null' Package name : '<NullPointerException>' 

In Java 9, this is no longer the case, instead an instance of Package is returned:

Class : 'class ClassInDefaultPackageTest' Package : 'package ' Package name : ''
