Timeout bug with http2jms transport, waiting for HTTP response 202 ACCEPTED (because of httpcore-4.0-beta1.jar and httpcore-nio-4.0-beta1.jar)
----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: ESBJAVA-593
                 URL: https://wso2.org/jira/browse/ESBJAVA-593
             Project: WSO2 ESB
          Issue Type: Bug
          Components: Core Engine
    Affects Versions: 1.7.1, 2.0
         Environment: Suse Linux 10 Enterprise Server, Windows XP Professional, 
            Reporter: Alexander Schleif
            Assignee: Ruwan Linton


Our test scenario: Like Synpase Example 251 (Axis2 1.4-Client -> WSO2 ESB1.7.1 -> ActiveMQ), difference: Client waits for HTTP Response 202 Accepted (in the example client sends the request with fireAndForget(), so you don't realize that bug ).

We had problems with the http2jms transport waiting on the client for a HTTP Response 202 Accepted: The JMS Message is alwasy delivered to JMS (ActiveMQ) at once, but sometimes it lasts to the socket timeout of the client (it was exactly the value of http.socket.timeout configured in the client) until it receives HTTP 202. The problem happens very often (>95% of the requests) on Linux (Suse Linux 10 ES),  rarely on Windows. But even on Windows sometimes the problem occured. When we debugged the code, we realized that the end of the chunks of the HTTP-reponse (0) ist not send to the client. So the the client does not recognize that the http response is already complete.

Our Solution:
Use the final versions of httpcore4 and http-nio4 (httpcore-4.0.jar,httpcore-nio-4.0.jar) instead of the beta versions (httpcore-4.0-beta1.jar, httpcore-nio-4.0-beta1.jar) in WSO2 ESB. They beta-versions are used both in WSO2 ESB1.7 and the WSO2 ESB2.0 .
Even Axis2 1.4 uses beta's of httpcore and httpcore-nio. I think it would be useful to replace them in Axis2, too.

Kind regards,
Alex
