constant references in enums

Here's a little puzzler:  Should this code compile, or is the forward reference illegal?

    enum FooE {
        FOOV(FOOC);  // ?? error: illegal forward reference
        FooE(int k) {}
        public static final int FOOC = 42;  // a constant variable
        // look, JLS 8.9.2 says "...unless the field is a constant variable"
    }

(I.e., should I file a bug if it fails to compile?)

Thanks,
— John
