The deploy process added log4j.jar for any plugins. This will cause errors in tomcat like following.

log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
log4j:ERROR The class "org.apache.log4j.Appender" was loaded by
log4j:ERROR [WebappClassLoader
delegate: false
repositories:
/WEB-INF/classes/
----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@1ac1fe4
] whereas object of type
log4j:ERROR "org.apache.log4j.ConsoleAppender" was loaded by [WebappClassLoader
delegate: false
repositories:
/WEB-INF/classes/
----------> Parent Classloader:
org.apache.catalina.loader.StandardClassLoader@1ac1fe4
].
log4j:ERROR Could not instantiate appender named "CONSOLE".
