java.net.useSystemProxies don't work with wagon-http-lightweight

In my job, we must use a "corporate proxy" with "NTLM+SPNEGO authentication" to access Internet.
Unfortunately, we haven't got any nominative proxy credential because Windows use current user session to authenticate against proxy (we we login to Windows session with a smart card).

The only way for Java application to connect to internet is to launch JVM with -Djava.net.useSystemProxies=true standard parameter.
It work perfectly with "standard" URLConnection , but unfortunately not with wagon-http-lightweight.
