JDK 6 Update 6 is out
You can find javac compilation issue with classes in javax.xml.ws.wsaddressing package in my previous blog "A little update for JAX-WS 2.1 users with JDK 6 Update 4 and Update 5"
The corresponding bug 6672868 is fixed in JDK 6 update 6.
The fix should be available in Open JDK 6 as well.
So, you don't have to use the compiler switches or workarounds as mentioned in my previous blog to make it work :)
