[jira] [Comment Edited] (CXF-4529) PermGen Leak for
CXFAuthenticator (WS Client Configuration)
[ https://issues.apache.org/jira/browse/CXF-4529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13476776#comment-13476776 ]

----------------------------------------------------------------
This is defenitely a classloader leak. CXFAuthenticator is loaded by webapp classloader and reference of this object is set to java system class, which is loaded by system classloader. So when application is unloaded, webapp classloader cannot be garbage collected, because CXFAuthenticator is referenced from java.net.Authenticator. This creates PermGen leak.
This issue must be reopened.

> Key: CXF-4529
> URL: https://issues.apache.org/jira/browse/CXF-4529
> Project: CXF
> Issue Type: Bug
> Components: Configuration, JAX-WS Runtime
> Affects Versions: 2.6.1
> Environment: Apache Tomcat 7, Windows 7 32bit
> Reporter: Holger Sunke
> Assignee: Freeman Fang
> Labels: leak, permgen
>
> Hello,
> seemes to me there is a memory leak with the CXFAuthenticator. There is a static reference to it in java.net.Authenticator.theAuthenticator .
> This prevents the GC from collecting the WebappClassLoader on hot undeployment.
> I helped myself by doing
> java.net.Authenticator.setDefault(null);
> on contextDestroy().
> Our web application uses CXF as a jasWS client configured with Spring 3.0.5.
