      Description

        As reported here:
        https://mail.openjdk.java.net/pipermail/compiler-dev/2021-August/017768.html

        A NPE should be reported for:
        ---
        public void foo(Object o) {
                switch (o) {
                  default: break;
                  case String s :System.out.println(s); break;
                }
        }
        public static void main(String[] args) {
                (new X()).foo(null); // NPE expected, but prints null
        }
        ---

        but it is not.
