Oneway CXF service having problem with Gemini-Web​/Tomcat-ca​talina
-------------------------------------------------------------------

                 Key: CXF-3609
                 URL: https://issues.apache.org/jira/browse/CXF-3609
             Project: CXF
          Issue Type: Bug
          Components: Transports
    Affects Versions: 2.3.5, 2.4.1
            Reporter: Aki Yoshida
            Assignee: Aki Yoshida
             Fix For: 2.4.2, 2.5


Hi, 
There seems to be some IO handling problem in oneway CXF services on 
equinox with the latest gemini-web. 
It think I have identified the cause of the problem and that we could 
fix it in CXF. But I would like to get your comments. 

The problem happens sporadically for oneway services when the 
StaxInInterceptor tries to instantiate the XMLStreamReader from the 
InputStream object. In this test scenario, a series of oneway calls 
are sequentially sent to a CXF oneway service. And sporadically, some 
calls result in the following exception, that is indicating the input 
stream is already closed, even though the data should be available in 
the stream. 

Caused by: java.lang.RuntimeException: Couldn't parse stream.

I didn't see this problem with jetty before and started to see this 
problem sporadically right after switching to gemini-web.
