Logging seemed to work fine when i was using AS 7.1 with log4j libs and code, now when using 7.2, i do not see the expected logging using log4j.

I follow the migration guide:

*Procedure 3.5. Configure JBoss Enterprise Application Platform 6 to use a log4 j.properties*
*or log4 j.xml file*
1. 1. Create a *jboss-deploym ent-structure.xm l* with the following content:
<jboss-deploym ent-structure>
<deploym ent>
<!-- Exclusions allow you to prevent the server from autom atically
adding som e dependencies -->
<exclusions>
<m odule nam e="org.apache.log4j" />
</exclusions>
</deploym ent>
</jboss-deploym ent-structure>
1. 2. Place the *jboss-deploym ent-structure.xm l* file in either the *MET A-INF/* directory or the
*WEB-INF/* directory if you are deploying a WAR, or in the *MET A-INF/* directory if you are
deploying an EAR.
1. 3. Include the *log4 j.properties* or *log4 j.xm l* file in the *lib/* directory in your deployment.
2. 4. Start the JBoss Enterprise Application Platform 6 server with the following runtime argument to
prevent a *ClassCastException* from appearing in the console when you deploy the application:
-Dorg.jboss.as.logging.per-deploym ent=false
1. 5. Deploy your application.


And then i get an exception that log4j classes cannot be found, which i would expect if i exclude log4j from the deployment.
