Mark Struberg commented on OWB-931:
-----------------------------------
Can you add a filter to your OSGi plugin system (like with blueprint and aries)?
The problem is really that the proxy get's injected into many places - visible
from many different ClassLoaders. And the only safe bet is to use the exact
same ClassLoader like the original class. It's not about the proxy can see the
protected methods of it's parent class, but more that other classes must see it
exactly the same way as the original class.
After all, a proxy is just a sub-class of the original class!

> NormalScopeProxyFactory classloader usage
> -----------------------------------------
>
> Key: OWB-931
> URL: https://issues.apache.org/jira/browse/OWB-931
> Project: OpenWebBeans
> Issue Type: Brainstorming
> Components: Core
> Affects Versions: 1.2.0
> Reporter: Moritz Bechler
> Labels: ClassLoader, OSGI
>
> createNormalScopeProxy currently uses the bean class ClassLoader for two
> purposes:
> 1. defining the proxy class
> 2. instantiation of the instance provider.
> In our OSGI/WAB environment this usage does not make much sense:
> 1. the proxy class should be defined in the classloader which most closely
> reflects the CDI context lifecycle, which is the web context TCCL.
> 2. causes trouble with scope providers (e.g OWB's own
> RequestScopedBeanInterceptorHandler) when they are defined in another bundle.
> I don't think there is a proper compatible solution to this (except maybe
> making extensions fragments) but also trying the TCCL makes this much more
> painless to use.
> Is there any explanation for this particular choice of classloaders? Are
> there any reasons not to try TCCL first?
