Reproduction steps

1. You can open the project using IntelliJ IDEA and then run the main method in the Test.java.
2. You can also build the project using Maven: mvn package,run it using java -jar target/log4j-1.0-SNAPSHOT.jar.

It will analyze the project located in the source directory, with the entry point being the main function in the org.apache.log4j.TestThrowableStrRep class.
