I am not aware of any place in HttpClient where it might meddle with the
interrupt flag. In any case I would recommend using
PoolingClientConnectionManager instead of the deprecated
ThreadSafeClientConnManager. If the problem still persists after
removing all references to deprecated code, the problem is more likely
to be caused by the AWS code.
