[jira] [Commented] (LOG4J2-3127) Log4j2 auto-initialization for servlet version 2.5

["Matt Sicker (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-3127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17384313#comment-17384313 ] 

Matt Sicker commented on LOG4J2-3127:
-------------------------------------

If you don't want auto-initialization with the servlet context, you can remove log4j-web from your classpath. This jar is only useful when you want to run multiple log4j2 configurations in the same servlet container which seems to be a less common usage pattern these days what with embedding Tomcat or Jetty instead of deploying to them.
