Connection is not released while using JAXWS client API
-------------------------------------------------------

                 Key: AXIS2-5062
                 URL: https://issues.apache.org/jira/browse/AXIS2-5062
             Project: Axis2
          Issue Type: Bug
          Components: jaxws, transports
    Affects Versions: 1.7.0
            Reporter: Ivan


1. Using Dispatch API
A bit more description for my case, the server side is a simple web service, for the client
side, the codes are something like :
--->
Service service = new HelloService();
Dispatch dispatchJaxb = service.createDispatch(PORT_QNAME, JAXBContext.newInstance(org.test.ObjectFactory.class),
javax.xml.ws.Service.Mode.PAYLOAD);
dispatchJaxb.invokeOneWay(new HelloRequest());
<---

After adding some code fragments in the finally block of BaseDispatch.invokeOneWay method,
it looks to me work fine.
--->
try {
                if (requestMsgCtx != null && requestMsgCtx.getAxisMessageContext()
!= null) {
                    org.apache.axis2.context.MessageContext axisMsgCtx = requestMsgCtx.getAxisMessageContext();
                    if (axisMsgCtx.getTransportOut() != null && axisMsgCtx.getTransportOut().getSender()
!= null) {
                        axisMsgCtx.getTransportOut().getSender().cleanup(axisMsgCtx);
                    }
                }
            } catch (Exception ignore) {
            }
<---

I also googled this issue, and do found a lot of information for the same timeout exception,
also read some related codes
a. In the HttpSender, there is a method named cleanup, which is used to release the connection,
but it has the precondition to configure the AUTO_RELEASE_CONNECTION. And actually I did not
see other setting configurations in the Axis2 codes, and think that it should be configured
by the users in the Options ? 
b. Some posts in the mail list recommended to call the getTransport().cleanup() in the Axis2
specific client codes. And in the testing scenario above, since the standard JAX-WS API is
used, suppose that Axis2 should do this ?
And very appreciated with any comment ? Thanks.

2. I might find another connection leak while using JAXWS API on client side. In the scenario
below :
For the server side, it requires basic authentication.

The client codes are something like :
HelloPort helloPort = (HelloPort)service.getPort(HelloPort.class);
helloPort.echo("hello");

The client codes did not set the user name and password by the BindingProvider interface,
so the server return a 404 to the client side, then the method HttpSender.handleResponse will
enter the fourth block :
private void handleResponse(MessageContext msgContext,
                                HttpMethodBase method) throws IOException {
        int statusCode = method.getStatusCode();
        log.trace("Handling response - " + statusCode);
        if (statusCode == HttpStatus.SC_OK) {
            // Save the HttpMethod so that we can release the connection when cleaning up
            msgContext.setProperty(HTTPConstants.HTTP_METHOD, method);
            processResponse(method, msgContext);
        } else if (statusCode == HttpStatus.SC_ACCEPTED) {
        	/* When an HTTP 202 Accepted code has been received, this will be the case of an
execution
        	 * of an in-only operation. In such a scenario, the HTTP response headers should
be returned,
        	 * i.e. session cookies. */
        	obtainHTTPHeaderInformation(method, msgContext);
        	// Since we don't expect any content with a 202 response, we must release the connection
        	method.releaseConnection();
        } else if (statusCode == HttpStatus.SC_INTERNAL_SERVER_ERROR ||
                statusCode == HttpStatus.SC_BAD_REQUEST) {
            // Save the HttpMethod so that we can release the connection when cleaning up
            msgContext.setProperty(HTTPConstants.HTTP_METHOD, method);
            Header contenttypeHeader =
                    method.getResponseHeader(HTTPConstants.HEADER_CONTENT_TYPE);
            String value = null;
            if (contenttypeHeader != null) {
                value = contenttypeHeader.getValue();
            }
             OperationContext opContext = msgContext.getOperationContext();
            if(opContext!=null){
                MessageContext inMessageContext =
                        opContext.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
                if(inMessageContext!=null){
                    inMessageContext.setProcessingFault(true);
                }
            }
            if (value != null) {

                processResponse(method, msgContext);
            }

            if (org.apache.axis2.util.Utils.isClientThreadNonBlockingPropertySet(msgContext))
{
            	 throw new AxisFault(Messages.getMessage("transportError",
                         String.valueOf(statusCode),
                         method.getStatusText()));
            }
        } else {
            throw new AxisFault(Messages.getMessage("transportError",   <--- Running here
                                                    String.valueOf(statusCode),
                                                    method.getStatusText()));
        }
    }
