Andreas Veithen commented on AXIS2-4898:
----------------------------------------
I was able to reproduce this using the version2 service provided by Sameera.
This should be fixed by r1056933 on the trunk. However, after stopping Axis2,
the Web app class loader is still not garbage collected. This is caused by
AXIS2-4263 (confirmed; workaround available) and AXIOM-354 (to be confirmed; no
workaround available).

> Shutting down Tomcat 6.0.29 gives the following error:
> Nov 23, 2010 4:42:18 PM org.apache.catalina.loader.WebappClassLoader
> clearReferencesThreads
> SEVERE: A web application appears to have started a thread named
> [MultiThreadedHttpConnectionManager cleanup] but has failed to stop it. This
> is very likely to create a memory leak.
> This error only happens when one of our Axis2 web services is called through
> a generated ADB client stub. It appears to never close this thread.
> Our current configuration on the web application:
> /**
> * The configureServiceStub method sets the web service client settings and
> * for the web service call.
> *
> * @param params WebServiceParameters
> *
> * @throws Exception
> */
> private void configureServiceStub(WebServiceParameters params) throws
> Exception
