Subject [jira] [Commented] (HTTPCLIENT-1122) NPE in RequestProxyAuthentication on Android
Date Fri, 02 Sep 2011 15:41:10 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13096054#comment-13096054
] 

Oleg Kalnichevski commented on HTTPCLIENT-1122:
-----------------------------------------------

Michael,

It is the same situation as with HTTPCORE-263. I really have no idea how to reproduce the
issue and suspect the problem might be a side effect of obfuscation with Proguard. I will
not be able to fix the problem without a reproducer.

> 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.
