>             Project: Log4j 2
>          Issue Type: Bug
>          Components: SLF4J Bridge
>    Affects Versions: 2.0-rc1
>         Environment: All (tried on Ubuntu 12 x64, Windows 7 x64, Mac OS X Maverick)

> The name of org.slf4j.impl.SLF4JLogger should indicate somehow that we are dealing with
Log4j 2.
> Right now the class is org.slf4j.impl.SLF4JLogger
> These are the names from other bindings:
>    nop     : org.slf4j.helpers.NOPLogger
>    simple  : org.slf4j.impl.SimpleLogger
>    jdk     : org.slf4j.impl.JDK14LoggerAdapter
>    jcl     : org.slf4j.impl.JCLLoggerAdapter
>    log4j   : org.slf4j.impl.Log4jLoggerAdapter
>    logback : ch.qos.logback.classic.Logger
>  Every one of them indicates what is the binding for, in the class name (all slf4j bindings),
or as part of package name (logback).
> Use case: "hook" into the functionality of the logger under slf4j to control stuff not
accessible through slf4j.
> Example: 
> http://code.google.com/p/okapi/source/browse/#git%2Fapplications%2Frainbow%2Fsrc%2Fmain%2Fjava%2Fnet%2Fsf%2Fokapi%2Fapplications%2Frainbow%2Flogger
> Code to reproduce this:
> =========
> import org.slf4j.Logger;
> import org.slf4j.LoggerFactory;
> public class LogHandlerFactory {
>     static public void main(String [] args) {
>         Logger localLogger = LoggerFactory.getLogger(LogHandlerFactory.class);
>         String realLogger = localLogger.getClass().getName();
>         System.out.printf("%-8s: %s%n", args.length > 0 ? args[0] : "???", realLogger);
>     }
> }
> =========
> Thank you,
> Mihai
