> CTS tests jaxws.ee.w2j.document.literal.async.client.invokeAsyncCallbackTest
> (for pojo, ejb and servlet client ) fail ocassionally. The reason being....
> In the invokeAsync method of JaxWsClientProxy class, ClientCallbacks
> handleMessage method is overridden. In this method first ClientCallbacks
> field done (boolean) is set to true and then handlers
> handleResponse(Response<?>) is called. In the CTS tests, if a
> ClientCallback.get() is called in between these two requests, a
> NullPointerException is thrown as the handlers state remains unchanged.
>
> Suggested Fix : synchronize the ClientCallbacks handleResponse in the
> JaxWsClientProxy.
> Also, ClientCallback class is a not thread safe so any state change
> should be done synchronously.
