MAPCodec : memory leak with an async client with network issues (connection timeout, read timeout
etc)
------------------------------------------------------------------------------------------------------

                 Key: CXF-2591
                 URL: https://issues.apache.org/jira/browse/CXF-2591
             Project: CXF
          Issue Type: Bug
          Components: WS-* Components
    Affects Versions: 2.2.5
         Environment: CXF 2.2.2 & 2.2.5 / JDK 1.6 / Linux (Ubuntu 9.10)
            Reporter: Thomas Sauzedde
            Priority: Critical


Context :
 a JAX-WS asynchronous client, with WS-Adressing enabled
 when there are network issues like connection timeout, read timeout etc,

Observed facts :
MAPCodec::uncorrelatedExchanges is not cleaned when the client is trying to request the server
and there is a network issue.

In such a case, the InterceptorChain is by-passed, so MAPCodec::handleFault() is NOT called
and so the MAPCodec::uncorrelatedExchanges grows and grows until OOM :-(

Don't have any patch (yet) to provide because this is something more architectural than technical
:-(

When a network issue occurs, this throws an ExecutionException in JaxwsClientCallback::handleResponse(),
the "normal" InterceptorChain is then by-passed there IMHO ...
