I just checked out AHC 1.9/Grizzly 2.3.21 and tried it with my code. It seems
to work ok but when I checked the http response header, it seems to be
missing. Was there a regression between 1.8 and 1.9? I traced down the code
and it looks like Grizzly does not call AsyncHandler.onHeadersReceived in
1.9
