I really don't think we should use ORO at all, now that Regexp is  
included in the JDK (since 1.4). We should really get rid of ORO.

I think it's going to be hard not to use any 1.4 features, especially  
as XWiki is based on 1.4 right now. We've already decided to stay 1.4  
compatible. I don't think we can decide to stay 1.3 compatible...

As Ludovic was saying, if we plan ahead, all mobiles devices will  
have a JDK 1.4 compliance level in not too long...

Note sure how this will help you though Pablo. We need to find a  
solution. Has anyone researched if there's a java.util.regexp  
implementation for 1.3?

Thanks
-Vincent
