Charles Barber commented on HTTPASYNC-85:
-----------------------------------------
Upgrading httpcore and httpcore-nio to 4.3.3 fixes it; thank you! Is that safe
to use with HttpAsyncClient 4.0.2 (any known incompatibilities), or should I
wait for the next HttpAsyncClient release that ships with HttpCore 4.3.3+?
Which issue / commit do you think would have affected this...I'm curious to
take a look.
I'm guessing not, but do you still want me to gather the logging output with
the 4.3.2 core / core-nio for any research purpose?

> ZeroCopyConsumer Hangs on SSL Download

> Key: HTTPASYNC-85
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-85
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Affects Versions: 4.0.2
> Environment: 2.6.18-398.el5 #1 SMP Tue Aug 12 06:26:17 EDT 2014
> x86_64 GNU/Linux
> Red Hat Enterprise Linux Server release 5.11 (Tikanga)
> java version "1.7.0_55"
> Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
> Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
> Reporter: Charles Barber
> Attachments: DemoSSLHang.zip

>
> When using the ZeroCopyConsumer class, but only when the target server is
> accessed over TLS, certain requests will result in it hanging indefinitely
> (until the other side resets the connection or the client times out), or for
> a couple minutes and then continue.
> This happens consistently against a .Net server in one of our partner's
> environments. I've also seen it when accessing a WebLogic 11g server, but
> with that, it will resume on its own after a couple minutes. I cannot
> reproduce it with a Jetty server.
> If I set up stunnel to do the TLS, and run exactly the same requests over
> plain text HTTP, we experience no issues. This is in fact our production
> workaround.
> Also, using the basic in-memory consumer (over TLS) works fine. I also wrote
> a simple async consumer that reads from the decoder to an array-based byte
> buffer and then writes to a file, and that works fine.
> Interestingly, I have another custom async consumer that we use for streaming
> back out to the original client, while HTTP Async Client is running in a
> servlet 3.1 container, and that hangs just like the ZeroCopyConsumer does
> (but again, no issue over plain text HTTP).
> I'll attach a client that can reproduce the error; unfortunately I can't
> provide the servers in question.
