Subject [jira] [Commented] (LOG4J2-223) IllegalStateException thrown during Tomcat shutdown
Date Sun, 19 May 2013 16:43:16 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13661597#comment-13661597
] 

Ralph Goers commented on LOG4J2-223:
------------------------------------

Remko stated above that if you use the BasicContextSelector with the Log4jContextListener
everything is good.  However, if you use the ClassLoaderContextSelector you still get the
message

FAIL - Unable to delete [C:\apps\apache-tomcat-7.0.40\webapps\log4j-223]. The continued presence
of this file may cause problems.

This implies that ClassLoaderContextSelector is hanging onto something.

You are correct that the LoggerContext adds the shutdown hook. I suppose the way to deal with
that is to add another attribute to the configuration element to enable the hook.
