Michael Pujos commented on HTTPCLIENT-1122:
-------------------------------------------
Now that I think of it, the app code related to the stack trace above does
indeed have plenty of HttpRequest.abort() going on while the request is
executing.
I'd say it has more aborting than usual, since requests are made to download
thumbnails images in a list, and requests are aborted during scrolling when
previously visible list item are now invisible.
> 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
> Fix For: 4.2 Alpha1
>
>
> 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.
> java.lang.NullPointerException
