Ok so this is not a regression, right?
But can it be your adapter that
doesn't flush the headers before
writing bytes? Can you share you
Adapter privately? Push it to
jfarcand at apache.org

Is FileCaching enabled? Looks like a bug with
FileCache *and* Grizzly
ARP. What is the size of the file?

---
filecaching isn't enabled

Ok that one it will be difficult to reproduce,
but there is clearly a
regression. I will go over the commit and see
what's happening. Can you
grab a network dump between the client and
the server?

Also, are you 100% sure IE 8 is the same version tested on
1.9.16 and
1.9.18?


---well, not totally sure, maybe wizoz update hit
me in this period :)
