What it says in the topic.
The problem appeared when we were migrating from GlassFish to Wildfly (10.0.0 Final). GlassFish appears to permit the SOAP message to be read by way of the context multiple times, which WildFly does not. According to asoldano on the IRC channel, multiple reads should be permitted.
Attached is a simple reproducer. Deploy it on GF and WF, and note the difference in replies to SOAP requests. I've attached the requests I've used, in both full dump format and a I'm Only Resting request file.
Is this a bug or a feature? Or am I just using WF completely wrong?
