> According to https://logging.apache.org/log4j/log4j-2.2/log4j-jcl/index.html the bridge should "just work". However since 2.21.0 log4j is no longer recognized, one needs to add the property file with
> {noformat}
> org.apache.commons.logging.LogFactory=org.apache.logging.log4j.jcl.LogFactoryImpl
> {noformat}
> this wasn't needed with 2.20.0. The attached project has the property file with a "_" ( _commons-logging.properties") one has to remove it to make the project work.
> What should happen:
> {noformat}
> 23.10.2023 11:03:49 INFO  log4j2reproducer.Main:21 - yeah
> {noformat}
> What actually happens:
> {noformat}
> Okt 23, 2023 11:03:09 AM com.mycompany.log4j2reproducer.Main doStuff
> INFORMATION: yeah
> {noformat}
