[read] I/O error: Socket is closed

[Marc Boorshtein]

I'm making calls to OpenPolicyAgent (Go based web server). GET calls work
great, but POST fails to get any content. When I turn on wire logging i
see:

but i'm not getting any content back from the output stream and i'm not
getting any exceptions. Here are my versions:

<httpclient.version>4.5.5</httpclient.version>
<httpcore.version>4.4.10</httpcore.version>
<httpmime.version>4.5.5</httpmime.version>

What else should I be looking for?

Thanks

Please post a snippet of your code and a _complete_ wire / context log
as an attachment.

Here's where I make the connection and do the request:
https://github.com/TremoloSecurity/OpenUnison/blob/1.0.15/unison/unison-server-core/src/main/java/com/tremolosecurity/proxy/postProcess/PushRequestProcess.java#L81

Here's the code i'm using to read the output stream:
https://github.com/TremoloSecurity/OpenUnison/blob/1.0.15/unison/unison-server-core/src/main/java/com/tremolosecurity/proxy/ConfigSys.java#L460

Attached is the full wire log for both a GET and a POST

Thanks
Marc

I realized i hadn't attached the logs you were looking for. I added the
context log in addition the wire log. I figured out the problem is i'm
asynchronously closing the connection object before the response
completes. Sorry for the false alarm.

Thanks
