When deploying an application in EAP 6 that has a log4j.xml that is deployed by the logging subsystem, it seems that the LogContext is somehow losing a reference to a custom logger, causing all configuration for that logger to be lost.

Given this configuration:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">
  <appender name="SAMPLE_APP" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${jboss.server.log.dir}/SampleApp.log"/>
    <param name="MaxFileSize" value="2MB"/>
    <param name="MaxBackupIndex" value="5"/>
    <param name="Append" value="true"/>
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d %c [%t] %-5p - %m%n"/>
    </layout>
  </appender>
  <appender name="SAMPLE_APP_MDB" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="${jboss.server.log.dir}/SampleApp-MDB.log"/>
    <param name="MaxFileSize" value="2MB"/>
    <param name="MaxBackupIndex" value="5"/>
    <param name="Append" value="true"/>
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d %c [%t] %-5p - %m%n"/>
    </layout>
  </appender>
  <logger name="com.redhat" additivity="false">
    <level value="TRACE"/>
    <appender-ref ref="SAMPLE_APP_MDB"/>
  </logger>
  <root>
    <priority value="TRACE"/>
    <appender-ref ref="SAMPLE_APP"/>
  </root>
</log4j:configuration>

Every log message ends up in {{SAMPLE_APP}}, regardless of which logger was used.  One finalizer message is also printed to the log:

11:33:00,110 INFO  [stdout] (Finalizer) log4j: Finalizing appender named [SAMPLE_APP_MDB].
