------------------------------------------------------------------------
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.
