Proxy generation use the bean instead of the interface
------------------------------------------------------
Key: ARIES-835
URL: https://issues.apache.org/jira/browse/ARIES-835
Project: Aries
Issue Type: Bug
Components: Blueprint
Affects Versions: blueprint-core-0.4.1
Reporter: Jean-Baptiste Onofré
In Karaf, we have a BlueprintCommand class looking like:
public class BlueprintCommand extends AbstractCommand implements
CompletableFunction
where AbstractCommand implements Function:
public abstract class AbstractCommand implements Function
We expose this as a service with the following blueprint definition:
<service>
<interfaces>
<value>org.apache.felix.service.command.Function</value>
<value>org.apache.karaf.shell.console.CompletableFunction</value>
</interfaces>
<service-properties>
<entry key="osgi.command.scope" value="*"/>
<entry key="osgi.command.function" value="help"/>
</service-properties>
<bean class="org.apache.karaf.shell.console.commands.BlueprintCommand">
<property name="blueprintContainer" ref="blueprintContainer"/>
<property name="blueprintConverter" ref="blueprintConverter"/>
<property name="actionId" value="help"/>
</bean>
</service>
So Aries Blueprint should generate a proxy with Function and
CompletableFunction.
However, it seems that Aries tries to generate a proxy with BlueprintCommand,
which is not correct:

org.apache.karaf.shell.console.commands.BlueprintCommand is not an interface
and therefore a proxy cannot be generated.
