Gary Tully updated CXF-1410:
----------------------------
Attachment: mt_context.patch
This patch implements a thread local request context that is refreshed with the
shared proxy requestContet map when getRequestContext is called.
Mods to the thread local requestContext map are echoed into the shared map so
they will be visible to subsequent calls to getRequestConctexts from other
threads.
This allows multiple threads to safely use a proxy with a different
ENDPOINT_ADDRESS property.
> Allow thread safe access to proxy with requestContext usage..

> It should be possible to cache a proxy and provide thread safe access to it.
> For example, the following code should work from multiple threads with
> deterministic results:
> Greeter greeter = // get cached proxy
> InvocationHandler handler = Proxy.getInvocationHandler(greeter);
> Map<String, Object> requestContext =
> ((BindingProvider)handler).getRequestContext();
> String threadSpecificaddress = // ...
> requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
> threadSpecificaddress);
> the proposal is to implement thread local request contexts and manage the
> mapping from shared proxy request contexts to the thread local.The
> synchronization point is on a call to getRequestContext. the return is a
> snapshot of the current shared proxy request context map.
> The map is such that it will echo modifications into the shared map. But
> further modifications to teh shared map will not be visible to the calling
> thread until subsequent getRequestContext call is made.
> In other words, an invoke works with a copy of the thread local context which
> takes into account modifications to the shared context at the time of the
> getRequestContextCall()
