Error at AsyncHttpClient

[s.abr...@emergecds.com]

Hi,

My company works with Play framework and Scala as our backend server. Lately we've been having problems with the server. While making a secured (SSL) request to a remote API, we're getting the exception below.

Seems to be a problem regarding to the SSL, but I'm not sure. 

We had a similar problem a month ago, and setting the certain flag: 
-J-XX:-UseAESIntrinsics -DXX:-UseAESIntrinsics 
seemed to help. Now the problem is back.

Some more information:

- Play 2.5.9

- Scala 2.11.8

- Server OS: Centos 6.8

- JVM 1.8.0_25-b17

The Exception:

 - AsyncHttpClient-2-4 - 2016-12-21 03:59:17,434 - [debug] - from org.asynchttpclient.netty.handler.HttpHandler - Unexpected I/O exception on channel [id: 0x9ad15e31, L:/[IP_ADDRESS:PORT - R:SERVER/IP_ADDRESS:443]

Does anyone have an idea what the problem could be and how can we fix it?

Thanks in advance,

This is a JVM bug, https://bugs.openjdk.java.net/browse/JDK-8067755 to be precise. Upgrade the JVM and it should be fine.
