Build Identifier: I20100608-0911

class OuterClassClash {
    static class Outer<T> {
        final T field;
        Outer(T val) {
            field = val;
        }

        class Inner {
            T get() {
                return field;
            }
        }
    }

    static class SubOuter extends Outer<Integer> {
        SubOuter(Integer val) {
            super(val);
        }

        class SubInner extends Outer<String>.Inner {
            /* Expected: "No enclosing instance of type Outer<String> is
             * accessible to invoke the super constructor..."
             * Actual: The Outer<Integer> enclosing instance is used, breaking
             * type safety. */
            SubInner() {}
        }
    }

    public static void main(String[] args) {
        Outer<String>.Inner obj = new SubOuter(42).new SubInner();
        String str = obj.get(); // ClassCastException
    }
}

The same bug exists in javac:
