Matt Pavlovich commented on KARAF-5664:
---------------------------------------

Yep, looks like its Felix, moving issue to Felix project

ref: org.apache.felix.framework.ServiceRegistrationImpl L327
{noformat}
        if ( m_factory != null )
        {
            props.put(Constants.SERVICE_SCOPE,
                      (m_factory instanceof PrototypeServiceFactory
                       ? Constants.SCOPE_PROTOTYPE : Constants.SCOPE_BUNDLE));
        }
        else
        {
            props.put(Constants.SERVICE_SCOPE, Constants.SCOPE_SINGLETON);
        }{noformat}

>                 URL: https://issues.apache.org/jira/browse/KARAF-5664
>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-scr
>    Affects Versions: 4.1.5
>            Reporter: Matt Pavlovich
>            Assignee: Jean-Baptiste Onofré
>            Priority: Major
>
> Project reproducing the issue is available here: [https://github.com/mattrpav/karaf-5664] 
> Steps to reproduce:
>  # Define a serviceComponent via xml (or osgi ds annotation)
>  # Deploy bundle
>  # run scr:info (observe Service Scope: singleton)
>  # run service:list (observe service.scope = bundle)
> Investigation:
>  * Debugging in felix.scr confirms that the xml is being parsed correctly and the returned
component metadata shows the 'scope' = 'singleton' correctly [o.a.felix.scr.impl.xml.XmlHandler#L362|https://github.com/apache/felix/blob/trunk/scr/src/main/java/org/apache/felix/scr/impl/xml/XmlHandler.java#L362]
>  * Debugging confirms that felix.scr is detecting DS13 namespace
>  scr:info output:
> {noformat}
> karaf@root()> scr:info TestModule
> *** Bundle: com.foo.test-module (124)
> Component Description:
> Name: BundleModule
> Implementation Class: com.foo.TestModule
> Default State: enabled
> Activation: immediate
> Configuration Policy: optional
> Activate Method: activate
> Deactivate Method: deactivate
> Modified Method: -
> Configuration Pid: [TestModule]
> Services: 
> com.foo.api.Module
> Service Scope: singleton
> Component Description Properties:
> Component Configuration:
> ComponentId: 4
> State: active 
> Component Configuration Properties:
> component.id = 4
> component.name = TestModule{noformat}
> service:list output
> {noformat}
> karaf@root()> service:list
> [com.foo.api.Module]
> ------------------------
> component.id = 4
> component.name = TestModule
> service.bundleid = 124
> service.id = 141 
> service.scope = bundle
> Provided by :
> Company :: Foo :: TestModule (124){noformat}
> OSGI-INF/serviceComponent.xml
> {noformat}
> <?xml version="1.0" encoding="utf-8"?>
> <scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.3.0"      name="TestModule"
immediate="true">
>     <service scope="singleton">
>         <provide interface="com.foo.api.Module" />
>     </service>
>     <implementation class="com.foo.TestModule" />
> </scr:component>{noformat}
>  
> Note: When the same impl class is reconfigured to register as a service via BundleActivator,
the service has a service.scope = 'singleton'
