Hi,

Log4j2 Fails to log the message provided correctly using the log4j-to-slf4j adaptor when the logging implementation used SLF4J-Simple.

To reproduce the issue use following class and configuration

HelloWorld.java 
--------------

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;


public class HelloWorld {

	private static final Logger logger = LogManager.getLogger("HelloWorld");
	
    public static void main(String[] args) {
        logger.error("Hello, World!");
        logger.error("Logging in user {} with birthday {}", "Ted", "1/10/1900");
    }

}

Jars in classpath
----------------------
log4j-api-2.0.1.jar
log4j-to-slf4j-2.0.1.jar
slf4j-api-1.7.7
slf4j-simple-1.7.7

The output generated is 
-----------------------------
[main] ERROR HelloWorld - org.apache.logging.log4j.spi.AbstractLogger
[main] ERROR HelloWorld - org.apache.logging.log4j.spi.AbstractLogger
