This is a bug report.
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("%b%n", b1.compareTo(b2));
System.out.printf("%b%n", b2.compareTo(b1));
}
}
==> javac -source 1.6 -Xlint:all BufferCompare.java
==> java -esa -ea BufferCompare
true
true
Is there any chance we might be allowed
to fix this violation of the Comparable contract?
If so, I volunteer to do so.
Martin
