[patterns] Null handling

[Remi Forax]

Apart if i've missed something, the implementation is not complete,
null handling is explicit, i.e.

 static void testSwitchNumber(Number i) {
   switch(i) {
   case 1: System.out.println("One");break;
   case null:
   default: System.out.println("Other");break;
   }
 }

cheers,
Rémi
