(was: I think the problem is not related to CXF but tomcat : [Bug

> Memory leak in tomcat webapp
> ----------------------------
>
> Key: CXF-6298
> URL: https://issues.apache.org/jira/browse/CXF-6298
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 3.0.4
> Environment: Tomcat 7.0.55
> Reporter: Alessandro Canevese
>
> I'm developing a J2EE webapp with Spring 4.1, Struts2, etc.. I'm not able to
> redeploy my app under development more than a couple of times before a
> permgen / out of memory error is fired.
> To see if it's my Spring configuration fault, I've got rid of the jaxws bean
> and I've put the following code directly in a method:
> ...
> 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>
> Nothing has changed. Sooner or later, when I undeploy the webapp I get a
> couple of the following:
> mar 12, 2015 5:46:05 PM org.apache.catalina.loader.WebappClassLoader
> 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$1@2379cbe3]) and a value of type
> [java.util.WeakHashMap] (value [
> {class
> it.cai.auth.ws.core.service.UserGroup=java.lang.ref.WeakReference@1138b647,
> class
> it.cai.auth.ws.core.service.GetUserDataResponse=java.lang.ref.WeakReference@2246f826,
> class java.util.ArrayList=java.lang.ref.WeakReference@614d985e, class
> it.cai.auth.ws.core.service.User=java.lang.ref.WeakReference@2d4e753a, class
> it.cai.auth.ws.core.service.Authority=java.lang.ref.WeakReference@79f24a12}
> ]) but failed to remove it when the web application was stopped. Threads are
> going to be renewed over time to try and avoid a probable memory leak.
> mar 12, 2015 5:46:05 PM org.apache.catalina.loader.WebappClassLoader
> checkThreadLocalMapForLeaks
> Grave: The web application [/soci-operativi] created a ThreadLocal with key
> of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@11dd224a]) and
> a value of type [org.apache.cxf.BusFactory.BusHolder] (value
> [org.apache.cxf.BusFactory$BusHolder@4cf6316f]) 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.
> Just to be clear, classes it.cai.auth.ws.core.service.* are those dynamically
> created by CXF accessing the ws pointed by the serviceUrl above.
