Of course, I spoke too soon. Having pushed a little further on with testing I reached the point where I could both deploy and exercise my services. I then found out that I was building against the old JBossWS libs but trying to run against the new ones which included this package change. I have fixed that and eventually I even managed to exercise some of my XTS tests. Basic request-reply JaxWS calls seem to be working ok but I am starting to see exceptions with tests which throw faults. I'll start a separate thread for that.
