---------------------------------------

             Summary: Blueprint interceptors do not work anymore
                 Key: ARIES-1793
                 URL: https://issues.apache.org/jira/browse/ARIES-1793
             Project: Aries
          Issue Type: Bug
          Components: Blueprint
    Affects Versions: blueprint-core-1.9.0
         Environment: Karaf 4.2.0
            Reporter: Nicolas Dutertry
         Attachments: aries-interceptor.patch

I have committed a project on Github to illustrate the issue : [https://github.com/nicolas-dutertry/test-jpa]

This project contains a blueprint bundle with a bean TestRepository annotated with @PersistenceContext.
This bean is then injected into another bean TestServiceImpl which is then published as an
osgi service :
{code:xml}
    <jpa:enable/>
    <tx:enable/>

    <!-- This bean contains a @PersistenceContext EntityManager -->
    <bean id="testRepository" class="com.dutertry.test.karaf.jpa.service.impl.TestRepository"/>

    <bean id="testService" class="com.dutertry.test.karaf.jpa.service.impl.TestServiceImpl">
        <property name="testRepository" ref="testRepository"/>
    </bean>

    <service interface="com.dutertry.test.karaf.jpa.service.TestService" ref="testService"/>
{code}
With Karaf 4.1.5 the instance of TestRepository injected in testService is an aries proxy
managing JPA stuff, but with Karaf 4.2.0 the injected instance is not a proxy. Thus when using
testService, the following error occurs:
{code:java}

After some investigation, I have found that this bug is due to the resolution of issue ARIES-1544.
I have done a patch (see attached file) which solve the issue I think.

[^aries-interceptor.patch]

Can you please integrate my patch or correct the issue another way ?
