Subject Re: Servlet & CDI Context Propogation

Hi Paul,

looks like it works as expected.

The default thread factory enforces the container classloader for worker
threads to avoid to leak which is fine but *tasks* are intended to set the
classloader (differentiate here banalised threads and user tasks).

replace your customer scheduled pool by an EE one and you will see how it
is supposed to work:

@Resource
private ManagedScheduledExecutorService
scheduledExecutorPoolWithManagedThreadFactory;
