Cached soap message cannot be deleted
-------------------------------------

                 Key: AXIS2-4577
                 URL: https://issues.apache.org/jira/browse/AXIS2-4577
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: kernel
    Affects Versions: 1.3
         Environment: Tomcat 5.5
            Reporter: Michael Yang


When caching is enabled in the axis2.xml file and MTOM is enabled, soap messages that are cached are unable to be deleted after processing is complete.  This can quickly consume a lot of storage as cached files will keep on accumulating without being deleted.  I have traced this bug back to the org.apache.axis2.builder.MIMEBuilder.processDocument(InputStream,String, MessageContext) method.  When creating an OMElement for the soap message, an inputstream to the cached soap message is obtained.  After the builder constructs the OMElement from cached soap message the inputstream is left open and the method returns.  This is the reason why the temporary cached files cannot be deleted as long while the server is still running.

The quick fix would be to just close the input stream after the OMElement is created.  I have include my simple solution to the bug below:  

 InputStream soapInput = attachments.getSOAPPartInputStream();  
        OMElement element = builder.processDocument(soapInput,
                                                    contentType, msgContext);
        try{
        	soapInput.close();
        }catch(Exception ex){
        	throw new AxisFault("Error closing inputstream to SOAP Part");
        }
