As far as I can tell, getDeclaredClasses always returns a zero-length array. Try running this:

class t {
    class b { }
    int i, j;
 
    public static void main(String[] args) {
        System.out.println(t.class.getDeclaredClasses().length + " classes");
        System.out.println(t.class.getDeclaredFields().length + " fields");
        System.out.println(t.class.getDeclaredMethods().length + " methods");
    }
}

The output I get with JDK1.1.1E is

0 classes
3 fields
2 methods

I presume that t.b should be returned.
