[jira] [Commented] (HTTPCLIENT-1279) NullPointerException
(apparently) when authenticating
[ 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.
