--------------------------
Attachment: AxisClient.zip
Attached Axis2 Client project along with the Jars used
> AxisConfiguration is NULL
> -------------------------
>
> Key: AXIS2-5777
> URL: https://issues.apache.org/jira/browse/AXIS2-5777
> Project: Axis2
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.7.2
> Reporter: Rajesh
> Attachments: AxisClient.zip
>
>
> Hi,
> Am using the axis2 1.7.2
> I have deployed the axis2.war in the tomcat and started the service. The
> StockQuoteService can be listened via the below url
> http://localhost:8080/axis2/services/StockQuoteService
> I have created a client to request that service (Attached the complete
> project zip).
> To trigger multiple requests, I have invoked the client call method in the
> For loop from main method
> To avoid creating the multiple connections, am caching the http client and
> reusing it.
> When I run the program with this setup, around 46 requests are executed
> successfully and returning the response. After that NPE in thrown.
> After investigating about it, found that the JVM is expelling the
> ServiceClient object
> ==========================================================
> ServiceClient.java
> ==========================================================
> protected void finalize() throws Throwable {
> try {
> cleanup();
> } finally {
> super.finalize();
> }
> }
> public void cleanup() throws AxisFault {
> // if a configuration context was created for this client there'll
> also
> // be a service group, so discard that
> if (!createConfigCtx) {
> String serviceGroupName =
> axisService.getAxisServiceGroup().getServiceGroupName();
> AxisConfiguration axisConfiguration =
> configContext.getAxisConfiguration();
> AxisServiceGroup asg =
> axisConfiguration.getServiceGroup(serviceGroupName);
> if ((asg != null) && removeAxisService) {
> axisConfiguration.removeServiceGroup(serviceGroupName);
> }
> } else {
> configContext.terminate();
> }
> }
> ==========================================================
> When the finalize method is called, it is invoking the cleaup method
> which again calls the terminate method of ConfigurationContext. Because of
> this
> AxisConfiguration in the ConfigurationContext is becoming NULL.
> Once this cleanup is done, the subsequent requests are not able to
> process due to empty AxisConfiguration returned from ConfigurationContext.
> This whole issue is due to reusing the HttpClient. When the HttpClient is not
> reused, this error is not thrown.
> But as per our project requirement, we will be getting multiple requests from
> the end user and we need to reuse the HttpClient.
> Kindly advice at the earliest, as we are facing this issue in the production
