[jboss-jira] [JBoss JIRA] Commented: (JBRULES-575) Shadow facts break when a fact Class has 2 properties (with a different name) of the same fact class

Edson Tirelli commented on JBRULES-575:
---------------------------------------

Ok, found the problem.

Java 5 allows you override a method changing its return type. In your case, Solution has a method clone() that returns a Solution object, while Match overrides the clone method returning a Match object. 

Need to improve proxy factory to override only the last overriden method: in this case, Match.clone(), and ignore parent overriden methods (Solution.clone() in your case).

> See user mailing list: [trunk] Repetitive field name/signature in class
> ava.lang.ClassFormatError: Repetitive field name/signature in class file net/sf/taseree/samples/travelingtournament/domain/MatchShadowProxy
> Here's my Match class:
> public class Match extends AbstractPersistable implements Comparable<Match>, Solution {
>     private Team homeTeam;
>     private Team awayTeam;
>     private Day day;
>     // getters, setters, clone(), toString()
> }
> AbstractPersistable has a Long id with getters/setters
> I will make a testcase with Cheese and provide a testcase patch, but it seems the trunk's pom's don't do "mvn idea:idea" properly, like the branch did,
> so I 'll provide a pom.xml patch first :)
