Doug Cutting commented on HADOOP-3262:
--------------------------------------
Sigh. I can't find a way to get a class that 'implements Delayed' to compile
in both Sun Java and Harmony.
Given:
{noformat}
public interface Comparable<T> {
int compareTo(T o);
}
public interface Delayed extends Comparable<Delayed> {}
{noformat}
Harmony requires the first of the following methods, but doesn't mind the
second, while Sun permits only the second.
{noformat}
public class DelayedImpl implements Delayed {
public int compareTo(Object o);
public int compareTo(Delayed o);
}
{noformat}
My hunch is that Sun is correct here and that we should file a bug against
Harmony.
