-------------------------------------
Summary: Web apps fail to start
Key: LOG4J2-1331
URL: https://issues.apache.org/jira/browse/LOG4J2-1331
Project: Log4j 2
Issue Type: Bug
Components: Web/Servlet
Affects Versions: 2.5, 2.4.1
Environment: Windows Server, Java 7, Tomcat 7, JSF 1.2
Reporter: Nicola Isotta
After upgrading from Log4j 2.3, my webapps fail to start after a Tomcat
restart. Actually, the first one starts correctly (even in multiple versions),
while the others' startup fails.
These are the causes:
SEVERE: Error configuring application listener of class
it.mycompany.filters.MyFilter
java.lang.NoClassDefFoundError: Could not initialize class

and, similar:

class org.apache.logging.log4j.web.Log4jServletContextListener
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.logging.log4j.core.lookup.MainMapLookup
SEVERE: Exception sending context destroyed event to listener instance of class
org.apache.logging.log4j.web.Log4jServletContextListener
java.lang.IllegalStateException: Cannot stop this Log4jWebInitializer because
it has not started.
This did not happen with 2.3. The only thing I did was changing the jars,
problem occurs with both 2.4.1 e 2.5.
