Nicolas Dutertry created ARIES-1793:
---------------------------------------
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}
java.lang.IllegalStateException: Need active coordination

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 ?
