Consider code like:
---
/**
 * @test /nodynamiccopyright/
 * @compile/fail/ref=SuperMethodCallBroken.out -XDdev -XDrawDiagnostics SuperMethodCallBroken.java
 */
public class SuperMethodCallBroken extends Undef implements I {
    public void test() {
        I.super.test();
    }
}
interface I {
    public default void test() {}
}
---

Compiling this will lead to:
---
$ javac SuperMethodCallBroken.java
SuperMethodCallBroken.java:5: error: cannot find symbol
public class SuperMethodCallBroken extends Undef implements I {
                                           ^
  symbol: class Undef

I.e. javac reports an error (correct), but then crashes with an exception:
