>         Environment: Apache Tomcat 9.0.68
> JDK Corretto 18

> In short: The loggers are altered before the handlers are added to the (root) logger. This leads to propers loggers but without any handler.
> My idea would be to move the propagation to a later point in time. So, I moved it to the method {{{}publish(){}}}. 
> Here is demo repo to reproduce the issue: [https://github.com/mknet/tomcat-webapp-log4j-jul-bridge]
> Here is the Pull Request with my approach to fix the issue: [https://github.com/apache/logging-log4j2/pull/1140]
