> Components: client-api
> Affects Versions: 1.5.1
> Environment: Operating system Windows and Linux
> Application Server: Tomcat 6.0.29
> Axis2 version 1.5.1
> Client created with ADB

> 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
> {
> // check if connection manager already established
> if(connectionManager == null)
> {
> connectionManager = new MultiThreadedHttpConnectionManager();
> connectionManagerParams = new HttpConnectionManagerParams();
> connectionManagerParams.setDefaultMaxConnectionsPerHost(2);
> connectionManagerParams.setTcpNoDelay(true);
> connectionManagerParams.setStaleCheckingEnabled(true);
> connectionManagerParams.setLinger(0);
> connectionManager.setParams(connectionManagerParams);
> httpClient = new HttpClient(connectionManager);
