support for JMS sonicMQ MultipartMessage

Hi,

I'm using soapui 5.1.3 with hermes 1.4.0

When I receive a MultipartMessage from an SonicMQ queue, I get an empty response pane and find following exception in error.log

ERROR:java.lang.NullPointerException
   java.lang.NullPointerException
    at com.eviware.soapui.impl.wsdl.WsdlSubmit.run(WsdlSubmit.java:125)
    at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471)
    at java.util.concurrent.FutureTask.run(FutureTask.java:262)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
    at java.lang.Thread.run(Thread.java:745)

In the hermes I find that the payload is empty an toString representation is progress.message.jimpl.xmessage.MultipartMessage@97edd9ac

Has anyone an idea how to fix this?
