After some micro bug fix releases on the 5.1 stream, JBossWS 5.2.0.Final has eventually been released.
The latest versions brings a lot of component upgrades to WildFly, the most relevant ones being Apache CXF 3.2 and JAXB 2.3. Thanks to many other minor improvements and fixes in the stack, the result is that JBossWS 5.2.0.Final is compatible (and has been tested) with the latest final JDK 9.
Please have a look at the release notes for further details and give it a try!
