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
