             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 org.apache.logging.log4j.util.PropertiesUtil
at org.apache.logging.log4j.status.StatusLogger.<clinit>(StatusLogger.java:78)
at org.apache.logging.log4j.web.Log4jServletContextListener.<clinit>(Log4jServletContextListener.java:44)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
…
at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4822)
…
{noformat}
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

 * log4j.message.ParameterizedMessageFactory
 * log4j.util.Constants
 * log4j.util.PropertiesUtil

 * java.util.ServiceConfigurationError

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.web.Log4jWebSupport log4j-web-2.17.2.jar
 * log4j.core.LifeCycle log4j-core-2.17.2.jar
 * log4j.web.Log4jWebLifeCycle log4j-web-2.17.2.jar
 * com.ofc.data.server.MyBatisConfiguratingContextListener from classes
 * com.ofc.data.server.CleanupContextListener from classes
 * log4j.web.Log4jServletFilter log4j-web-2.17.2.jar
 * … other classes

 * java.lang.invoke.LambdaForm$…
 * log4j.util.EnvironmentPropertySource
 * log4j.util.SystemPropertiesPropertySource
 * log4j.util.PropertiesUtil.$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.
