      Description

      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:
