Example:

    public class Test
    {
        static class Outer
        {
            Outer(Inner inner) { }

            interface Inner { void f(); }
        }

        static class Foo extends Outer
        {
            Foo() { super(new Inner() { public void f() { Foo.this.notify(); } }); }
        }
    }

No error is shown in the editor, although the code is not legal.
Compiling with the external compiler (javac 1.6) correctly produces the following error message for the super() line:

    no enclosing instance of type Test.Foo is in scope
            Foo() { super(new Inner() { public void f() { Foo.this.notify(); } }); }
