Issue
My goal is to have all app-level logging go to my app log file. My problem is that while a lot of my debug/info/error messages make it to STDOUT/File etc... here is one error that only shows in my tomcat9 log:
4-Jun-2018 08:55:29.050 SEVERE [http-nio-82-exec-6] org.apache.catalina.core.ApplicationDispatcher.invoke Servlet.service() for servlet [jsp] threw exception

I am using jdk 10, Spring 5.0.5, Hibernate 5.3, Logback 1.2.3

Seems like JSP/view/tiles/dwr errors are the ones I am missing in STDOUT
Solution
This Servlet related exception logs are handled by Tomcat internal logging library which is a customised java.util.logging.
According to this :
The calls to javax.servlet.ServletContext.log(...) to write log messages are handled by internal Tomcat logging. Such messages are logged to the category named
org.apache.catalina.core.ContainerBase.[${engine}].[${host}].[${context}]
To overwrite the global Tomcat logging configuration , try to put a java.util.logging 's properties file logging.properties in /WEB-INF/classes/ and configure the above logger log to a file handler , somethings like this:
handlers =java.util.logging.FileHandler
java.util.logging.FileHandler.level = INFO
java.util.logging.FileHandler.formatter = org.apache.juli.OneLineFormatter
java.util.logging.FileHandler.pattern = /temp/app.log
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = java.util.logging.FileHandler
