Consider this code:
---
/**
 * @test
 * @compile/fail/ref=SuperConstructorCallBroken.out -XDshould-stop.at=FLOW -XDdev -XDrawDiagnostics SuperConstructorCallBroken.java
 */
public class SuperConstructorCallBroken extends Undefined1 {
     public SuperConstructorCallBroken(int i) {
         new Undefined2() { public void test(int i) { Undefined3 u; } }.super();
     }
     interface I<T> {}
}
---

Compiling it may lead to:
---
$ ~/tools/jdk/jdk-15/bin/javac -XDshould-stop.at=FLOW -XDdev test/langtools/tools/javac/recovery/SuperConstructorCallBroken.java
test/langtools/tools/javac/recovery/SuperConstructorCallBroken.java:5: error: cannot find symbol
public class SuperConstructorCallBroken extends Undefined1 {
                                                ^
  symbol: class Undefined1
