Subject [jira] [Created] (CXF-4480) Client generated with "-db source" and using streaming doesn't work properly with messages > 10 kb
Date Tue, 21 Aug 2012 13:05:38 GMT
Andrei Shakirin created CXF-4480:
------------------------------------

             Summary: Client generated with "-db source" and using streaming doesn't work
properly with messages > 10 kb
                 Key: CXF-4480
                 URL: https://issues.apache.org/jira/browse/CXF-4480
             Project: CXF
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.6
            Reporter: Andrei Shakirin
            Priority: Critical


Use case: client is generated from WSDL using -db source option and uses streaming to send
message payload concurrently. Service is implemented using Provider<> interface and
just redirects incoming request to response.

Test results:

1. Combination works fine if message size is 1 KB. Client succesfully runs in single thread
and in concurrent modes.

2. If message size is 10 KB (or larger), after some time client becomes following exceptions:

Errors occure in concurrent as well as in non-concurrent modes, but are easily reproducable
in concurrent case.

Eventually problem is related to message chunking.

Test projects are attached.
