Spring WS attachments- SaajSoapMessage vs AxiomSoapMessage

Question

I have a spring web service which accepts multi-part files in requests. I was using default SaajSoapMessageFactory and testing my web service with SoapUI. When I attach multiple files with the request and when trying to access them at the service endpoint with ((SaajSoapMessage) messageContext.getRequest()).getAttachments(); I got only one attachment which has to contentId of first attachment.

When I found that default SaajSoapMessageFactory has some issue of handling attachments tried to use AxiomSoapMessageFactory. And now I am getting the error org.xml.sax.SAXParseException; problem accessing the parser. Parser already accessed!

Any solution for this?

EDIT: I am using PayloadRootAnnotationMethodEndpointMapping with Jdom2.Element for @RequestPayload. Is there any cause from it?

Edit: When I have set both payloadCaching and attachmentCaching properties to true, soapUI is giving

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>soapenv:Server</faultcode>
         <faultstring xml:lang="en">java.lang.NullPointerException</faultstring>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>
