Remko Popma commented on LOG4J2-223:
------------------------------------
I also tried my fix in Tomcat 6.
Here, I don't get the 500 error.
The logging.jsp page shows the message "Messages have been logged.", and the
output from the taglib logs is correctly logged to the console and
/logs/application.log file.
My hello-world page also shows the expected output.
Unloading the webapp does not give warnings, it just says "Undeploying web
application at context path /log4j-223" (in Japanese, the English may be
slightly different).
Shutting down Tomcat-6 after that with Ctrl-C now gives this stack trace:
