WorldServer versions 11.1.0. , 11.1.1. and 11.2.x, although they are using log4j 1.x, they also contain log4j 2.6.2 as a transitive dependency.
In order to mitigate this issue for log4j 2.2.2, we need to remove the JndiLookup.class from within log4j-core-2.6.2.jar\org\apache\logging\log4j\core\lookup\
Attached to this article, you will find a jar file with the class removed. You can either use it, or just make a copy with it removed by yourself.
You will need it to replace the existing one in the following locations:
Optional (recommended) is to also replace it within the war files (can be done with 7zip for example):
Important: If you have any customization or Hotfix that uses configuration files, you can simply move the WAR files outside of the tomcat/webapps folder. Webapps in Tomcat doesn’t require the WAR files to be there after they were initially expanded. This way you can make sure nothing gets wrongfully re-updated.
WorldServer (Idiom Service) should be restarted after this change.
In a multi-server environment, the change and restart must be deployed on each Application Server
on which WorldServer is deployed.Note: this issue will be permanently solved in the upcoming WorldServer 11.7.2. where log4j 2.17 will be used.
