Oleg Kalnichevski commented on HTTPCORE-650:
--------------------------------------------
[~horizonzy] I understand this is inconvenient for you as a user but there are
other users of this library as well. You will have to patch HttpCore locally if
you are not willing to work on finding out the root cause of the defect.
