I have a few questions on interceptors:<br>
<br>
</div>
1. CDI Interceptors on cdi beans<br>
</div>
Will the interceptors share the same creational
context as the bean it is associated with?</div>
</div>
</div>
</div>
</div>
</div>
</blockquote>
Yes. It is not the very same creational context but a new one with a
parent-child relationship to the one of the associated bean. This is
the same as for @Dependent dependencies<br>

the old-styled interceptors?<br>

Yes, Weld manages interceptor bindings associated using interceptor
bindings as well as those associated using @Interceptors<br>

<div>@Interceptors don't work on other cdi beans except
ejb and managed beans, right?<br>

"Managed bean" is ambiguous. Weld support interceptors on all CDI
managed beans (not on producer fields/methods nor extension-provided
beans).<br>

2. Interceptors on ejb beans or managed beans<br>
</div>
I think the integrator needs to create these @Interceptors
and cdi interceptors.</div>
</div>
</div>

Yes, for EJBs and EE managed beans it is integrator's job to handle
those. Weld can handle @AroundConstruct interceptors if needed. I've
updated the docs on this topic recently:

<div> Will these interceptors use the non-contextual

ejb or managed bean's creational context

Will Weld destroy the interceptors when the associated
beans are destroyed or the integrator need to destroy
them? This logic applicable to both cdi interceptors and
@Interceptors style interceptors, right?<br>
</div>
</div>
</div>
</div>
</blockquote>
Any time the parent (bean's) creational context is destroyed, the
children creational contexts (interceptors') are destroyed also by
Weld.<br>

3. Interceptors on JavaEE components<br>
</div>
I think this interceptors are created by Weld when the JavaEE
component classes are created, right? By the way, how can the
container make sure to destroy the interceptors?<br>
</div>
</div>
</blockquote>
This depends on how the component classes are managed. Assuming the
components are managed using Weld-provided InjectionTarget then it
is up to the integrator to decide whether it provides interception
support or whether it should be provided by Weld. This can be
configured for each InjectionTarget individually using this builder:
