So now that I'm starting to code exceptions and messages that will show up in management console tools, I need to start thinking about how this will be internationalized. We have a couple of starting points:

http://docs.jboss.org/process-guide/en/html/internationalization.html#d0e3916

and a project John mentioned and has written about:
http://www.onjava.com/pub/a/onjava/2006/12/06/i18n-messages-and-logging.html?page=2
http://i18nlog.sourceforge.net/doc/users-guide.html

I like the i18nlog annotations for handling the bundle keys, but the logging is a subset of the arjuna code. Maybe the best approach is just to update the arjuna javadoc to use annotations similar to i18nlog.
