Let's see:

1. Write interface(s) with a method for each thing you want to log 
(annotated of course).
2. Add a maven plugin to generate code in your project
3. add generated code to your project
4. add X classes to your project and the permgen space associated with them.
5. Create a hard dependency to JBoss Logging or yet another maven plugin 
to shade in that dependency


vs.

log.info(ID, Object... args);
String msg = localization.generateMessage(ID, Object... args);


2 function calls compared to X extra Classes, Y extra methods, Z extra 
annotations, one extra maven plugin, generated code, and an extra hard 
library dependency unless you shade it in with an additional maven plugin.

To gain:

* in all probability, an array index instead of a hash lookup to locate 
a message format.
* "Type safety".  for an interface that has *ONLY ONE REFERENCE* and of 
which type safety is meaningless considering all you're doing is 
generating strings.

Yup, pretty much a behemoth.
