I've recently upgraded from 8.0.15 to 8.0.18 and I have a new problem which I
didn't have on 8.0.15. The configuration of tomcat and my application remained
exactly the same when upgrading.
When running tomcat with
-DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
(defined in setenv.sh) to enable log4j2's async logging, I now get a
ClassNotFoundException (see below). What could be the problem?
Here's catalina.out with FINE level logging for org.apache.jasper.servlet:
