Timothy Ward commented on ARIES-703:
------------------------------------
The code committed under revision 1240203 should make things much better. I was
even able to remove ASM from the transaction itests and they kept working
(which wasn't possible before)
I hope this helps!
> JDKProxyManager cannot proxy blueprint beans

> Key: ARIES-703
> URL: https://issues.apache.org/jira/browse/ARIES-703
> Project: Aries
> Issue Type: Bug
> Components: Blueprint
> Environment: Glassfish 3.1
> Reporter: Balazs Zsoldos
> Assignee: Timothy Ward
> Fix For: blueprint-0.4.0

>
> When there is no ASM between the bundles and aries proxy is installed the
> default proxy manager is JDKProxyManager. When there is a bean in a blueprint
> fragment that has for example tx:transaction inside creating the
> transactional proxy fails with the following stacktrace:

> It will always happen as we have the following line in BeanRecepe:
> intercepted = BlueprintExtender.getProxyManager().createInterceptingProxy(b,
> ProxyUtils.asList(original.getClass()), original,
> new Collaborator(interceptorLookupKey, interceptors));
> That means that the interface list is the class of the bean itself that is
> cannot be an interface. In case of JDKProxy we should derive the interfaces
> that the bean implements and those interface classes should be passed.
> However at this level (BeanRecipe) we do not know about the proxy manager...

> <jpa:context property="em"
> unitname="biz.everit.audit.persistence.entity" type="TRANSACTION" />
> </bean>
