Sorry, this is an oversight: https://issues.jboss.org/browse/JBWS-3381
We need to provide an up-to-date container integration module for the latest AS 7.0.x target.
As a temporary workaround while the jira above is being worked, you can use either AS 7.0.0 or the current AS 7.1.0-Beta2-SNAPSHOT (with the current jbossws-native 4.0.0-SNAPSHOT)
