Deltaspike Core - MessageBundle

[Juliano Marques]

Hi,

I'm trying to do this:

@MessageBundle
public interface I18N {

    @MessageTemplate("{system.title}")
    String systemTitle();

    @MessageTemplate("{welcome.user}")
    String welcomeUser(String user);

    @MessageTemplate("{number.of.sessions}")
    Integer numberOfSessions(); // this does not work.
}

When I deploy my application, I get the following error:
java.lang.IllegalArgumentException: The following MessageBundle problems 
where found: [int isn't supported. Details: 
br.com.dominiosistemas.messages.I18N#numberOfSessions only 
java.lang.String or org.apache.deltaspike.core.api.message.Message]

So, MessageBundle does not support @MessageTemplates with another type 
than String or Message.
My question is: why?
This is not adressed by documentation or Javadoc in @MessageBundle or 
@MessageTemplate.

Thanks for the help. Apache Deltaspike is great.
Atenciosamente,
