Broker is logging into file system by default instead only to console on openshift

Since 7.11.0 (ENTMQBR-7157) brokers deployed by the operator was logging to console only (the pod log) and the file system files .../log/artemis.log .../log/audit.log were empty.

On 7.11.2 the file .../log/artemis.log has contents now. 

As I see the change in the default broker log4j created this regression.

As I see the main change is on

rootLogger.level = INFO
rootLogger.appenderRef.console.ref = console
rootLogger.appenderRef.log_file.ref = log_file

which were befere:

rootLogger = INFO, console
