<p class="MsoNormal">Yes the org.jboss.logmanager:log4j-jboss-logmanager can be used as a replacement of log4j. The only requirement is that the org.jboss.logmanager:jboss-logmanager also be on the class path. That is what we use with the shipped zips. We do
not ship an Apache log4j library.<o:p></o:p></p>

https://github.com/bstansberry/wildfly.git</a>. I understand this is the latest and is from the principal maintainer, Brian Stansberry. I've changed the pom references to the old log4j-v1 to the new log4j-v2 but a pom dependency analysis reveals there is a
still a dependency on v1. I am at a loss as to where exactly it is coming from. I hope someone here can shed some light please.<o:p></o:p></p>
