I have my log4j settings in my grails app with version 2.4.3. And my log4j version inside the lib folder is 1.2.17 (the compatible version of grails 2.4.3). Due to the log4j exploit issue, I need to upgrade my log4j version to 2.16.0. How can I do the necessary configurations to point my existing grails app to the latest log4j?
