Pull request #4376 regressed compilation of all inner classes using <enclosing class>.super pattern in their constructor argument to fail with:
 error: cannot reference super before supertype constructor has been called

Following source fragment can be used as a minimal test case:
    class EnclClass {
        class InnerClass extends Exception {
            InnerClass() {
                super(EnclClass.super.toString());
            }
        }
    }
