Subject [jira] Commented: (MYFACES-2942) Memory Leak in MyFaces 2.0.1 probably as well in 2.0.2
Date Sat, 11 Dec 2010 11:24:01 GMT

    [ https://issues.apache.org/jira/browse/MYFACES-2942?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12970449#action_12970449

Andrei Zagorneanu commented on MYFACES-2942:
--------------------------------------------

Is it resolved for MyFaces 1.2.x also? I'm using MyFaces 1.2.9 and I'm getting the following
when I'm stopping Tomcat:

11.12.2010 12:55:04 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: The web application [/foe-web-app] created a ThreadLocal with key of type [java.lang.ThreadLocal]
(value [java.lang.ThreadLocal@9eca0a]) and a value of type [org.apache.myfaces.config.RuntimeConfig]
(value [org.apache.myfaces.config.RuntimeConfig@e28500]) but failed to remove it when the
web application was stopped. This is very likely to create a memory leak.
11.12.2010 12:55:04 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: The web application [/foe-web-app] created a ThreadLocal with key of type [null] (value
[org.apache.myfaces.el.convert.VariableResolverToELResolver$1@1414d1e]) and a value of type
[java.util.HashSet] (value [[]]) but failed to remove it when the web application was stopped.
This is very likely to create a memory leak.

> Stan Silvert from JBoss reports:
> I'm pretty sure 2.0.1 has a memory leak on undeploy.  Mojarra had an undeploy leak and
it took a long time to track it down.  The same test I was using on Mojarra also failed on
MyFaces but I haven't had time to track down the leak in MyFaces.
> Maybe this is fixed in 2.0.2?  If not maybe someone can go ahead and take a look?  The
mem leak keeps MyFaces from passing TCK on JBoss AS.  To test, all you need to do is create
a small exploaded JSF app.  Then have a script that touches web.xml every 10 seconds.  That
will cause the app to redeploy.  You will get a PermGen error in about an hour.
