Root Cause Analysis of Missing Logs after Tomcat 7→8 Upgrade

After upgrading from Tomcat 7 to Tomcat 8, the application’s mixed log4j‑1.4 and logback‑1.2.3 dependencies caused the SLF4J binder to be loaded nondeterministically, so Tomcat 8 sometimes selected the Log4j binder without a configuration file, resulting in completely missing log output; removing the conflicting jars or enforcing a deterministic class‑loading order restored logging.
