Tomcat 9 error on WAR deployment tries to read logging configuration from wrong location

Question

I have a Spring Boot WAR application deployed into a Tomcat 9 installation in a server.

It worked fine until another tool created a configuration file in the server. After this, every time Tomcat launches it fails to deploy the WAR file. It seems to me it is looking at this file as if it was a logging configuration file and somehow the Spring Boot app looks at this as a logging configuration file.

The Spring Boot app has the default logging config, there is no XML file with custom logging configuration. The only thing I have is in the .properties a logging.file.name property which never worked in the server, only when running locally. I even tried renaming the config file in the server but the Tomcat logs still show the same error. Tomcat is installed in a completely different folder than the logging_config.ini file.

Any idea why Tomcat/Spring Boot would be looking at this config file on launch?

I checked the catalina.sh file, checked the logging.properties file, renamed the ini file, looked for the file name through all the Tomcat files and found nothing.
