Subject [jira] [Commented] (HTTPCLIENT-1173) NoSuchElementException in org.apache.http.impl.cookie.BestMatchSpec.formatCookies
Date Wed, 14 Mar 2012 21:02:34 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13229608#comment-13229608
] 

Oleg Kalnichevski commented on HTTPCLIENT-1173:
-----------------------------------------------

I can't find anything wrong with the code just based on this exception stack trace. RequestAddCookies
always creates a local instance of List<Cookie> [1]. So, this can't be a threading issue.
 BestMatchSpec does not explicitly call ArrayList#Itr.next. It uses 'for each' loop to iterate
list items [2]. 

I will not be able to do much without a reproducer.
