----------------------------------------
Summary: NoClassDefFoundError initializing PropertiesUtil in
Servlet 2.5 container
Key: LOG4J2-3624
URL: https://issues.apache.org/jira/browse/LOG4J2-3624
Project: Log4j 2
Issue Type: Bug
Components: API
Affects Versions: 2.18.0
Environment: Apache Tomcat/8.53
Linux 4.14.1294-220.533.amzn2
amd64
JVM 1.8.0_3420-b07, Red Hat. Inc
Reporter: Nicholas Sushkin
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

With log4j 2.17.2, there is no exception and {{Log4jServletFilter}} initializes
fine.
I traced class loading during the web application initialization.
With 2.18.0, the following classes are loaded:
* log4j.web.Log4jServletContainerInitializer log4j-web-2.18.0.jar
* log4j.Logger log4j-api-2.18.0.jar
* log4j.web.Log4jServletContextListener log4j-api-2.18.0.jar

With 2.17.2, it goes like this:
* log4j.web.Log4jServletContainerInitializer log4j-web-2.17.2.jar
* log4j.Logger log4j-api-2.17.2.jar
* log4j.web.Log4jServletContextListener log4j-api-2.17.2.jar

* log4j.util.PropertiesUtil.$Environment$$Lambda
!http://localhost:1313/ox-hugo/workspaces_vBkgFs3RKy_2022-10-27_15-50-13.png!
In 2.8.0, log4j.util.PropertiesUtil.$Environment$$Lambda is loaded but not
invoked.
It looks like there are recent changes in
log4j.util.PropertiesUtil.$Environment in commits aaf13561e7 Piotr Karwasz
2022-03-10, 262828b193 2022-04-13. These are changes for LOG4J2-3427.
