Hi,
I have noticed the following issue with the grizzly 1.9.18-SNAPSHOT libs,
but only in a production system; I have not been able to reproduce on
my development machine.
During a client POST to a grizzly SSL server, a buffer underflow in the
SSLEngine leads to an EOFException. This in turn causes the http connection
to be dropped, and the client aborts the POST.
Hopefully you can work out what is going on from the trace log below.
However, if you need more information please let me know, and I can increase
my efforts to reproduce it on my development machine (although it may be
tricky to consistently produce a TCP stream which results in such a buffer
underflow).
Any help is appreciated!
Kind regards,
Tom
