In terms of exception handling, of course you are right in terms of
final product.
IIUC that not how use of jboss-logging for generating exception messages
is supposed to work, though to be honest, I do not know the details.
Since you "use this in Validator and Search" I would figure you would
know how to do it.
The "purpose of the annotation processor" is couple-fold, but here the
intention is to handle i18n of the logged messages, same as it would for
exception messages that you want...
