Andreas Veithen commented on AXIS2-5874:
----------------------------------------
* The contract of {{DataHandler}} allows multiple calls to
{{getInputStream()}}. That means that requesting the stream and closing it will
not free the memory held by the {{DataHandler}}.
* The fact that you get an {{OutOfMemoryError}} in the code that reads the MIME
part does not mean that the (presumed) leak occurs there. You will need to look
at a heap dump to determine where references to the objects involved in the
leak are held. There is no a priori reason to believe that it's Axis2's fault;
it may be a problem in your code.
* 1.6.2 is an old release that is no longer supported. You would need to
provide steps to reproduce the problem on a more recent release.

> Key: AXIS2-5874
> URL: https://issues.apache.org/jira/browse/AXIS2-5874
> Project: Axis2
> Issue Type: Bug
> Components: jaxws, wsdl
> Affects Versions: 1.6.2
> Environment: Windows 2008
> Reporter: Nidhin Lazar
> Priority: Blocker
>
> We are using AXIS WS to connect and download files from an external
> repository .We are using SOAP based webservice calls download an object. The
> API returns a DataHandler object, from where we are getting the input stream.
> We have tried closing the inputstream object but even after the close call we
> can see that the memory is still holding the stream, and eventually the
> client machine is running out of memory.Any help on this would be highly
> appreciated.
> Our client code is as shown below
> URL url = new URL("http://"+host+"/ws/CntSrvc.svc?wsdl";);
> CntSrvc_Svc cService = new CntSrvc_Svc(url);
> CntSrvc cntSrvcClient = cService.getBasicHttpBindingCntSrvc(new
> MTOMFeature());
> InputStream in = null ;
> in = cntSrvcClient.download(contextIDString).getInputStream();
> // write in to a file.
> //closing the input stream
> if (in != null){
> in.close();
> }
> [Note;] Our client code runs under tomcat container, and this acts as a
> server to other services.
> [Note:]We have created a sample client without using AXIS, where our client
> connecting to external repository and download content.Here we donot see any
> memory leak.Our investigation proves that its when we use AXIS and
> getinputstream() the memory is leaking, input stream is not closing.Our
> current framework demands AXIS hence we would like to get a solution or
> workaround for this issue
