Of course you're right.  Here's what I really meant:

import java.nio.*;

public class BufferCompare {
    public static void main(String[] args) {
        DoubleBuffer b1 = DoubleBuffer.wrap(new double[] { Double.NaN });
        DoubleBuffer b2 = DoubleBuffer.wrap(new double[] { 1.0 });
        System.out.printf("%d%n", b1.compareTo(b2));
        System.out.printf("%d%n", b2.compareTo(b1));
    }
}
==> javac -source 1.6 -Xlint:all BufferCompare.java
==> java -esa -ea BufferCompare
