Hi Sielaah ,
Extract the jar file and then search for the above files and remove those and convert the folder to jar again.
But make sure after making these changes, your penatho server starts.
Since I made the same changes to the data-integartion/lib/log4j file , but the server didn't run properly.
Let me know if it works for you.
The best option seems to migrate to log4j-2.17 version
