> The configuration I have in Tomcat 8 and Java 1.8 with the Servlet 2.5 style initialization works in 2.17.2, but breaks in 2.18.0 (and 2.19.0) with the following exception:
> {noformat}
> [localhost-startStop-1] Error configuring application listener of class org.apache.logging.log4j.web.Log4jServletContextListener
> java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil

> {noformat}
> With log4j 2.17.2, there is no exception and {{Log4jServletFilter}} initializes fine. 
> I traced class loading during the web application initialization.
