Questions about "JAX-WS client proxies thread safery"

Hi everyone,

I have a question regarding "JAX-WS client proxies thread safery". (See
http://cxf.apache.org/faq.html#FAQ-AreJAX-WSclientproxiesthreadsafe?) .

If at application startup I configure a client proxy with a fixed "HTTP
Basic auth" login/password and then share this proxy between multiple
threads will that be safe ? (After startup, no thread will modify the client
configuration hence all threads using same login/password)

Same question if I set up a client with a fixed WSS UsernameToken at startup
and then share this client between my threads will that be safe ?

Thanks in advance for your help.
