We are trying our best to keep the JDK up to date with latest JAX-WS RI. The recently released JDK 6 Update release 14 has JAX-WS 2.1.6 RI along with JAXB 2.1.10 RI. You can find more about the changes that went in to the release can be seen at JAX-WS 2.1.6 change log and JAXB 2.1.10 change log. I hope the JAX-WS users find this helpful.
