Danielius Jurna commented on CXF-4529:
--------------------------------------
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
classloadee cannot be garbage collected, because CXFAuthenticator is referenced
from java.net.Authenticator. This creates PermGen leak.
This issue must be reopened.

> 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.
