Andreas Veithen commented on AXIS2-5203:
----------------------------------------
Basically, your analysis is limited to the fact that JAXWSMessageReceiver
creates a _new_ class loader for every request (and therefore your logical
conclusion is to cache that class loader), while I would go a step further and
say that the very fact that it creates a class loader and the way it creates
it are problematic. If I get the time tonight I will try to construct an
argument that clearly shows that the original code which creates this class
loader is incorrect.
> JAX-WS Message Receiver Adds a new URL class loader to TCCL per each request.

> In Current JAX-WS Message Receiver its adds a new URL class Loader instance

> And also this may cause OOM situation since at AXIOM level it cache the
> XMLOutput factories per class Loader by default. So in this case the Hash map
> entries that's used for this cache will get accumulated.
