Java doesn't support the %u format. Using a trick from StackOverflow gives the same results:

public class HighBits {

    public static void main(String... argv) {
        long HIGH_BITS =  0xFFFFFFFF << 28;
        System.out.printf("%d\n", HIGH_BITS);
        System.out.printf("%d\n", HIGH_BITS & 0xFFFFFFFFL);
    }
}
