repositories example throws NoSuchMethodError due to conflicting log4j versions
-------------------------------------------------------------------------------

                 Key: DNA-500
                 URL: https://jira.jboss.org/jira/browse/DNA-500
             Project: DNA
          Issue Type: Bug
          Components: Examples
    Affects Versions: 0.6
         Environment: JBoss DNA revision 1142

java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.5) (ArchLinux-1.5-5-i686)
OpenJDK Server VM (build 14.0-b15, mixed mode)
            Reporter: torkjel hongve


When launching the repositories example (using run.sh from target/dna-example-repositories-basic.dir/) I immediately get the following error: 

Exception in thread "Thread-1" java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z
        at org.slf4j.impl.Log4jLoggerAdapter.isTraceEnabled(Log4jLoggerAdapter.java:81)
        at org.jboss.dna.common.util.Logger.isTraceEnabled(Logger.java:411)
        at org.jboss.dna.graph.connector.map.MapRepositoryConnection.execute(MapRepositoryConnection.java
etc...

This is due to the lib direcotry containing both log4j-1.2.14.jar and log4j-1.2.8.jar. 1.2.14 is the correct one and contains the isTraceEnabled method, but version 1.2.8 is the one being used at runtime. 

"mvn dependency:tree" shows the following dependendy paths to log4j: 

[INFO] +- log4j:log4j:jar:1.2.14:compile
[INFO] +- org.jboss.security:jbosssx-bare:jar:2.0.2.SP6:compile
[INFO] |  +- org.jboss.security:jboss-security-acl-impl:jar:2.0.2.SP6:compile
[INFO] |  |  +- jboss:jboss-logging-log4j:jar:2.0.2.GA:runtime
[INFO] |  |  |  \- apache-log4j:log4j:jar:1.2.8:runtime
