Glassfish 3.1
Description
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...
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>
