>             Project: CXF
>          Issue Type: Bug
>          Components: Transports
>    Affects Versions: 2.7.6, 2.7.7, 2.7.8, 2.7.9, 2.7.10, 2.7.11
>         Environment: Windows or Linux
>            Reporter: Nicolas Sprauel
>            Assignee: Daniel Kulp
>            Priority: Critical

> This issue occurs when using the asynchronous conduit (use.async.http.conduit set to
true), AND with the environment proxy configuration set (http.proxyHost, http.proxyPort, and
http.nonProxyHosts properties set).
> The end of the AsyncHTTPConduit.setupConnection() method calls:
> <code>
>         Proxy p = proxyFactory.createProxy(csPolicy , uri);
>         if (p != null) {
> </code>
> When the http.nonProxyHosts property matches the target server host, then the ProxyFactory.createProxy()
method returns Proxy.NO_PROXY, and not null. This means that because p is not null, the next
2 lines are executed:
> <code>
>             InetSocketAddress isa = (InetSocketAddress)p.address();
>             HttpHost proxy = new HttpHost(isa.getHostName(), isa.getPort());
> </code>
> p.address() returns null as expected, which means that the next line (line 200 in release
2.7.6) causes a NullPointerException, and crashes the call.
> The fix would be simple, by replacing:
> <code>
>         if (p != null) {
> </code>
> with
> <code>
>         if (p != null && !p.type() == Proxy.Type.DIRECT) {
> </code>
