Someone can base on that, can break compatibility

> {code:java}
> @Namespace("/do")
> public class CRUDAction {
>     /* [1] specific wildcard */
>     @Override @Action(value="some/usefull/{stuff}",results={@Result(location = "result.jsp")})
>     public String execute() throws Exception {...}
>     /* [2] less specific wildcard */
>     @Override @Action(value="some/{stuff}", results={@Result(location ="result.jsp")})
>     public String input() throws Exception {...} 
> }
> {code}
> Currently pattern [2] due to greedy natching catches every "/do/some/\{stuff}" AND "/do/some/usefull/\{stuff}"
event.
> For instance while calling /do/some/eating or /do/some/usefull/sleeping will both end
in [2] where stuff becomes "eating" or "usefull/sleep" respectively, [1] is left behind with
nothing to do.
> The expected matching behaviour should always be from more specific to less specific.
> I.e. [2] should never fire before [1]. So that /do/some/usefull/sleeping would correctly
map to [1] with stuff==sleeping and /do/some/eating correctly maps to [2] with stuff==eating.
> Using xml one can achieve the correct matching order by re-ordering the action definitions
(most specific action mapping comes first)
