Which version of JAX-WS is included in Java 8?

Which version of JAX-WS is included in Java 8? "wsimport -version" produces "2.2.9" but this version is not available on https://jax-ws.java.net

My application uses JAX-WS for XML Web Services. I am going to migrate it to Java 8. To do this I need to put correct version of jars to my class path (to be compatible with included in JRE version of JAX-ws) .

Please advise.

Thanks!
