[logback-user] Shibboleth IDP logs stopped generating after tomcat upgrade to 9.0.31

Hi All, We have been using shibboleth IDP and we noticed that the logs stopped generating after we upgraded tomcat from 9.0.15 to 9.0.31. No changes have been made to logback.xml. I have also checked that logback-core, logback-classic and slf4j-api jar files are present. Can anyone please guide us on how to troubleshoot this issue. Thanks, Regards, Kshitij Chug
