I tried to setup log4j2 via xml configuration but when I tried
"display" command I could see this exception:

Error executing command: Unable to set level for logger
my org.ops4j.pax.logging.cfg contains:
org.ops4j.pax.logging.log4j2.config.file=${karaf.etc}/log4j2.xml
and log4j2.xml:
<Configuration id="builtin.rolling">
<Appenders>
<Console name="console">
<PatternLayout pattern="%logger/%class [%level] %message%n" />
</Console>
<RollingFile name="file" append="true">
<fileName>logs/service.log</fileName>
<filePattern>logs/service.log.%d{yyyy-MM}</filePattern>
<PatternLayout pattern="%logger/%class [%level] %mdc %message%n" />
<Policies>
<TimeBasedTriggeringPolicy />
</Policies>
</RollingFile>
</Appenders>
<Loggers>
<Logger name="my.logger" level="info" additivity="false">
<AppenderRef ref="file" />
</Logger>
<Root level="debug">
<AppenderRef ref="console" />
</Root>
</Loggers>
</Configuration>
My environment is Fedora Linux F35 and openjdk 17.0.1.
Could someone give me any hint what is wrong with this setup?
best regards
Jakub
