This week (28 February 2006) nightly build. The server is JAX-WS 2.0 bundled httpserver. Authentication is enabled (thanks to filter).
A JAX-WS client creates a port then send a request without credentials ==> Exception is thrown. This is fine.
The client then creates a new port, provides credentials, then sends the request again ==>
Response never received.

If the client does the opposite (secured then unsecured), it works fine!

I attached a client, a server, the BasicFilter and a small wsdl to reproduce.
