> Key: HARMONY-5807
> URL: https://issues.apache.org/jira/browse/HARMONY-5807
> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Affects Versions: 5.0M5
> Reporter: Doug Cutting
> Assignee: Tim Ellison
> Attachments: DelayedImpl.java, HARMONY-5807.patch

>
> In HADOOP-3262 I tried to get Hadoop to compile under Harmony, and ran into a problem.
> I can't find a way to get a class that 'implements Delayed' to compile in both Sun Java and Harmony.
> Given:
> public interface Comparable<T> {
> int compareTo(T o);
> }
> public interface Delayed extends Comparable<Delayed> {}
> What is the correct signature for compareTo() in a Delayed implementation. Harmony requires the first of the following methods, and doesn't mind the second, while Sun permits only the second.
> public class DelayedImpl implements Delayed {
> public int compareTo(Object o);
> public int compareTo(Delayed o);
> }
> My guess is that Sun is correct and that this is a bug in Harmony. Is that right?
