Subject [jira] [Commented] (HTTPCLIENT-1173) NoSuchElementException in org.apache.http.impl.cookie.BestMatchSpec.formatCookies
Date Wed, 30 Jan 2013 23:59:13 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13567119#comment-13567119
] 

Bill van Melle commented on HTTPCLIENT-1173:
--------------------------------------------

For what it's worth, this just happened to me, too (under Windows 7 / Oracle Java 7.0), and
my program has very few theads.  The error occurred quite a few times before I noticed it
(my code catches errors and quietly retries after a few seconds).  I happened to be running
under the debugger at the time, so I set a breakpoint on the line in question in formatCookies.
 Looked pretty innocent (there were the expected two cookies), and as you say, it can't be
a threading issue, given that you're working on a local copy.  After a couple of times around
the debugger the problem cleared itself up.
