Can you provide a test case that reproduces this behavior? Created attachment 186627 [details]
RSConsumer (error comes up here)
Created attachment 186628 [details]
RSProvider
I have added a test case (very simple!). Please use the *.launch files to start an appropriate environment. First start the RSConsumer, then the RSProvider. The error occurs on the RSConsumer side. I would be very pleased about hints for a fix or workaround. You don't get any exception on the provider end? No exception on provider end. Created attachment 186713 [details]

Please provide patches to the two existing projects. New projects make it hard to track your changes and incorporate them with mine. (In reply to comment #10) > Please provide patches to the two existing projects. New projects make it hard > to track your changes and incorporate them with mine. Okay, I just added the service interface also to the RSConsumer (was missing there). But nothing changed so this was not the problem. Can you set a breakpoint in org.eclipse.ecf.internal.osgi.services.distribution.DiscoveredServiceTrackerImpl.registerRemoteServiceReferences(RemoteServiceEndpointDescription, IRemoteServiceContainer, IRemoteServiceReference[]) line 583 and issue "services" on the console when it's hit?

The FIRST service registered is not null, it is: remoteReferences = [RemoteServiceReference[remoteServiceID=org.eclipse.ecf.remoteservice.RemoteServiceID[containerID=r-osgi://jumper:9279;containerRelativeID=52];ref=RemoteServiceReference{r-osgi://jumper:9279#52-[services.ServiceA]}]] remoteService = org.eclipse.ecf.internal.provider.r_osgi.RemoteServiceImpl@74c12978 (In reply to comment #14) > (In reply to comment #13) > > (In reply to comment #12) > > > Can you set a breakpoint in > > > org.eclipse.ecf.internal.osgi.services.distribution.DiscoveredServiceTrackerImpl.registerRemoteServiceReferences(RemoteServiceEndpointDescription, > > > IRemoteServiceContainer, IRemoteServiceReference[]) line 583 and issue > > > "services" on the console when it's hit? > > > > remoteReferences = > > [RemoteServiceReference[remoteServiceID=org.eclipse.ecf.remoteservice.RemoteServiceID[containerID=r-osgi://jumper:9279;containerRelativeID=54];ref=RemoteServiceReference{r-osgi://jumper:9279#54-[services.ServiceA]}]] > > > > remoteService = null > > > > So null of course does come from remoteServiceContainer > > .getContainerAdapter().getRemoteService(...) > > The FIRST service registered is not null, it is: > > remoteReferences = > [RemoteServiceReference[remoteServiceID=org.eclipse.ecf.remoteservice.RemoteServiceID[containerID=r-osgi://jumper:9279;containerRelativeID=52];ref=RemoteServiceReference{r-osgi://jumper:9279#52-[services.ServiceA]}]] > > remoteService = > org.eclipse.ecf.internal.provider.r_osgi.RemoteServiceImpl@74c12978 I think it could be something on provider end or with the R-OSGi Container of course... I need the output of "services" issued on the console when the breakpoint is hit. (In reply to comment #16) > I need the output of "services" issued on the console when the breakpoint is > hit. Hi Markus, sorry I'm not sure what to do, I don't have a "services" var there.

Hm, it does seem to fix this bug in the test case (given here) but it's not bug free in my full case. There I are services beeing registered roughly the same time. Open a new bug or stay with this? I think they could have similar reasons...
Now there is this ERROR ("getRemoteServiceReferences result is empty") sometimes not, and often also with an Exception on provider side:
I'll look at this again tomorrow. Good luck and thanks for your help!
