Alessandro Canevese commented on CXF-5492:
------------------------------------------
I'm getting a similar problem with release 3.0.4 when undeploying a tomcat
application with a Spring jaxws generated bean.
To see if it's Spring fault, I've got rid of the jaxws bean and I've put
directly in a method the following code:
...
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(serviceUrl + "?wsdl");
Object result = null;
try
{
Object[] callResult = client.invoke(methodName, parameter);
result = callResult[0];
}
catch (Exception ex)
{
log.error(ex);
}
...use of result (without storing it anywhere)...
<end of method>
When I undeploy the webapp I get a couple of the following:

checkThreadLocalMapForLeaks
Grave: The web application [/soci-operativi] created a ThreadLocal with key of
type [com.sun.xml.bind.v2.ClassFactory$1] (value
[com.sun.xml.bind.v2.ClassFactory$1@2379cbe3]) and a value of type
[java.util.WeakHashMap] (value [{class

but failed to remove it when the web application was stopped. Threads are going
to be renewed over time to try and avoid a probable memory leak.

the web application was stopped. Threads are going to be renewed over time to

where, say, it.cai.auth.ws.core.service.User is a CXF dynamically created class.
