Subject [jira] [Commented] (HTTPCLIENT-1279) NullPointerException (apparently) when authenticating
Date Tue, 05 Apr 2016 08:54:25 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15225914#comment-15225914
] 

Tobias Oberlies commented on HTTPCLIENT-1279:
---------------------------------------------

The stacktrace from a 4.1.3 httpclient in this case is
{noformat}
java.lang.NullPointerException
	at org.apache.http.impl.client.DefaultRequestDirector.updateAuthState(DefaultRequestDirector.java:1211)
	at org.apache.http.impl.client.DefaultRequestDirector.handleResponse(DefaultRequestDirector.java:1131)
	at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:492)
	at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:820)
	at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:754)
	at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:732)
{noformat}

I searched for this bug but had a hard time to find it because the stack trace was missing.
