Description

Steps to reproduce:
1. Replace contents of etc/org.ops4j.pax.logging.cfg with

org.ops4j.pax.logging.log4j2.config.file=${karaf.etc}/log4j2.xml

2. Add an etc/log4j2.xml configuration file with a configuration like

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info">
    <Appenders>
        <PaxOsgi name="paxosgi" filter="VmLogAppender"/>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="paxosgi"/>
