Andreas Veithen commented on AXIS2-4673:
----------------------------------------
The condition inStream.available() > 0 does NOT check for an empty input
stream! Please have a look at the relevant Javadoc.
> 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.
