The logging framework was upgraded from log4j to log4j2 (v2.17.1) to address a critical vulnerability. As part of the log4j update a new log4j2.properties file is used for setting log configuration properties.
This project was updated to be a maven project.
The pom.xml file manages most of the dependencies and includes them in a jar with dependencies when the project is built with:
mvn package
Dependency jars which cannot be found in the maven central repository are included in the lib folder.
