        Description

        The following causes a runtime crash. The class Object declares a 'registerNatives' method, and this is what gets resolved for the call from 'main'. This condition was not properly accounted for in JVMS 7; the Lambda Spec considers this an IAE (per 5.4.3.4). (Still, a fix should probably be backported -- this does not depend on new 8 features.)

        public class RegisterNatives {
          interface I { void registerNatives(); }
          interface J extends I {}
          static class B implements J { public void registerNatives() { System.out.println("B"); } }
          public static void main(String... args) {
            J val = new B();
            val.registerNatives();
          }
        }
