             Summary: Defining karaf.log.console as a log4j2 log level causes exceptions
                 Key: KARAF-5116
                 URL: https://issues.apache.org/jira/browse/KARAF-5116
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.1.1
            Reporter: Jamie Kemp
            Priority: Minor


Running karaf 4.1.1, defining karaf.log.console as DEBUG to switch on the console appender (to get to logging when running under pax-exam) results in the following exceptions:

Looks like BootstrapLogManager attempts to use java.util.logging levels which DEBUG is not one of them. This however does result in valid logging out via log4j2 to the console appender. 

Using a valid java.util.logger level (tried FINE during testing) results in logging to the console from 'SimpleFileLock' but nothing from log4j2.
