Re: An Unexpected I/O exception with AsyncHttpClient while performing SSL requests

[Seán Coffey]

Your JDK version is quite old. Try updating to the latest JDK 8u release.

this might be a factor and was fixed in 8u51.

Hi everyone,

I was referred to this group and I hope this is the right place and would really appreciate if you could share your opinion with me.

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 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

The Exception:

  * AsyncHttpClient-2-4 - 2016-12-21 03:59:17,434 - [debug] - from

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

Also, is there any other place you know where I could get help about this topic?

Thanks in advance,
