      Description

        this program:

        import java.util.stream.*;

        public class Test {
          interface I {}
          static abstract class C { }
          static class A extends C implements I { }
          static class B extends C implements I { }

          static String f(I i) { return null; }

          public static void main(String[] args) {
            Stream.of(new A(), new B())
              .map(Test::f)
              .forEach(System.out::println);
          }
        }

        is accepted by the compiler but fails with LCE at execution time. Reported at: http://mail.openjdk.java.net/pipermail/compiler-dev/2018-October/012569.html
