[jira] [Commented] (CXF-4529) PermGen Leak for CXFAuthenticator (WS Client Configuration)

Petr Nídl commented on CXF-4529:
--------------------------------

And there is another problem related to this one. When you have two (or more) applications deployed to application server, each of them using CXFAuthenticator, and you stop one of them, the alive one will fail to proceed with authentication task because the still registered CXFAuthenticator fails to load its necessary classes because is classloader is already marked as stopped. On Tomcat this looks like this:
{code}
Nov 15, 2012 9:24:19 PM org.apache.catalina.loader.WebappClassLoader loadClass
INFO: Illegal access: this web application instance has been stopped already.  Could not load org.apache.cxf.message.MessageImpl.  The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
java.lang.IllegalStateException

	at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1597)
	at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1556)
	at org.apache.cxf.endpoint.ClientImpl.getConduit(ClientImpl.java:835)
	at org.apache.cxf.endpoint.ClientImpl.destroy(ClientImpl.java:206)
	at org.apache.cxf.frontend.ClientProxy.finalize(ClientProxy.java:94)
	at java.lang.ref.Finalizer.invokeFinalizeMethod(Native Method)
	at java.lang.ref.Finalizer.runFinalizer(Finalizer.java:83)
	at java.lang.ref.Finalizer.access$100(Finalizer.java:14)
	at java.lang.ref.Finalizer$FinalizerThread.run(Finalizer.java:160)
{code}
But I suppose that this problem really is unresolvable and the solution is to use Commons HTTPClient for HTTP Conduit (CXF-291)

> 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.
