Mike Rheinheimer commented on AXIS2-4673:
-----------------------------------------

Ah, right... so what's the better way?  I'd rather not do read() and reset() just to check it.  That could have the side effect of resetting further back than the current marker.

> Currently, the org.apache.axis2.transport.TransportUtils.createSOAPMessage correctly throws an exception for a null InputStream, but passes an empty InputStream down to the parser, which may throw an exception resulting in an exception stack similar to:
> Throwable occurred: org.apache.axiom.om.OMException: javax.xml.stream.XMLStreamException: The root element is required in a well-formed document.
