NPE in RequestProxyAuthentication on Android
--------------------------------------------

                 Key: HTTPCLIENT-1122
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1122
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.1.1
         Environment: Android 2.3.4. Using repackaged httpcore 4.1.1 in an app obfuscated
with Proguard.
must be very rare as I only saw it once for > 10K users.
            Reporter: Michael Pujos
            Priority: Minor


Got a NPE backtrace in RequestProxyAuthentication.process(). 

HttpRoute route = conn.getRoute();
        if (route.isTunnelled()) {      <= line 88, NPE here
            return;
        }

There's no null check on the returned route although getRoute() can return null.
I guess it's not supposed to happen.

In the httpclient code, there's a few more calls to getRoute() without a null check on the
returned route.
