Description

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 ...
