             Summary: Logstash TCP-Input throws "Bad record MAC" when trying to connect with WildFly over SSL/TLS
                 Key: WFLY-7338
                 URL: https://issues.jboss.org/browse/WFLY-7338
             Project: WildFly
          Issue Type: Bug
    Affects Versions: 10.1.0.Final, 10.0.0.Final
            Reporter: Patrick Kleindienst
            Assignee: Jason Greene


I use the jboss-logmanger-ext library for transfering log records to Logstash over a secure socket. For that purpose, my Logstash TCP-Input config authenticates with WildFly by means of a self-signed certificate. However, some time after SSL handshake has started, the following exception is thrown:

{code:java}

{code}
    
On the Logstash side, the following error message appears in the logs:
{code}
:message=>"An error occurred. Closing connection", :exception=>#<IOError: bad record MAC>
{code}

Afterwards, WildFly hangs forever without deploying my webapp or doing anything else. Before that happens, the handshake goes through these phases:

* *** ClientHello, TLSv1.2
* *** ServerHello, TLSv1.2
* %% Initialized:  [Session-1, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256]
* Found trusted certificate
* *** ECDH ServerKeyExchange
* *** ServerHelloDone
* *** ECDHClientKeyExchange
* SESSION KEYGEN:
* CONNECTION KEYGEN:
* *** Finished
   
When disabling SSL both on WildFly and Logstash side, everything works fine.
