Subject [jira] [Commented] (LOG4J2-426) Permgen leak: Log4j2 does not unregister MBeans on shutdown
Date Thu, 07 Nov 2013 16:37:18 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13816103#comment-13816103
] 

Jon Larry commented on LOG4J2-426:
----------------------------------

I'm not getting uniquely registered jmx LoggerContext either. Added log4jContextName and log4jConfiguration
context-params in  web.xml and am using org.apache.logging.log4j.core.web.Log4jServletContextListener
servlet-listener of two different web apps.
(version 2.0-beta9)

Resulting in a single LoggerContext Mbean:
.  org.apache.logging.log4j2:type=LoggerContext,ctx=AsyncLoggerContext

Also the mbean attributes for the AssyncLoggerContext are incorrect:
.   configLocation=file:/Applications/eclipse-cequint/Eclipse.app/Contents/MacOS/CCDB
.   configText=FileNotFoundException...

I would have expected the configLocation to reflect the log4j2 file that was loaded and configText
to contain the xml in that file.

> Subj. This causes permgen leak on undeploying web applications which uses log4j2.
> Also, as far as i can see, there is no support exposing multiple log4j2 contexts via
JMX which can be nice for web applications.
