Andreas Veithen commented on AXIS2-4673:
----------------------------------------
I agree with Rich. Since TransportUtils.createSOAPEnvelope is used by most of
the transports and an empty payload is invalid in that context (unless the
message builder decides otherwise), we should not introduce hacks to work
around specific problems in Sandesha.
> kernel TransportUtils.createSOAPEnvelope should return empty envelope for
> empty InputStream

> 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.
