JDKProxyManager cannot proxy blueprint beans
--------------------------------------------
Key: ARIES-703
URL: https://issues.apache.org/jira/browse/ARIES-703
Project: Aries
Issue Type: Bug
Components: Proxy
Environment: Glassfish 3.1
Reporter: Balazs Zsoldos
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:

Caused by: org.apache.aries.proxy.UnableToProxyException: The class
biz.everit.audit.persistence.impl.EventPersistenceServiceImpl is not an

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...
The example blueprint file for this:
<bean id="eventPersistenceImpl"
class="biz.everit.audit.persistence.impl.EventPersistenceServiceImpl">
<tx:transaction method="*" value="Required" />
<jpa:context property="em"
unitname="biz.everit.audit.persistence.entity" type="TRANSACTION" />
</bean>
