| Subject: Exception using RemoteServices |

I am using a container for both remote services and distributed event admin:
final IRemoteServiceContainerAdapter rsc = (IRemoteServiceContainerAdapter) ((IAdaptable) container).getAdapter(IRemoteServiceContainerAdapter.class);
rsc.addRemoteServiceListener(new IRemoteServiceListener() {
@Override
public void handleServiceEvent(IRemoteServiceEvent event) {
String targetClass = StateProvider.class.getName();
String[] clazzes = event.getClazzes();
boolean quit = false;
for (int i = 0; !quit && i < clazzes.length; i++)
quit = clazzes[i].equals(targetClass);
if (quit) try {
IRemoteServiceReference ref = event.getReference();
IRemoteService rs = rsc.getRemoteService(ref);
IRemoteCall call = new RemoteCall("provideState");
Map<String, Object> state = (Map<String, Object>) rs.callSync(call);
syncBundles(state);
} catch (Exception x) {Log.log(Log.ERROR, x.getMessage());
disconnect();}
}
});
final ISharedObjectContainer soc = (ISharedObjectContainer) ((IAdaptable) container).getAdapter(ISharedObjectContainer.class);
soc.addListener(new IContainerListener() {
@Override
public void handleEvent(IContainerEvent event) {
if (event instanceof IContainerConnectedEvent)
try {
ISharedObjectManager manager = soc.getSharedObjectManager();
admin = new DistributedEventAdmin(context);
ID id1 = IDFactory.getDefault().createStringID("uk.co.xlegal.xbundle3.remote");
Properties props = new Properties();
props.put(EventConstants.EVENT_TOPIC, "uk_co_xlegal_xbundle3_remote");
manager.addSharedObject(id1, (ISharedObject) admin, props);
((DistributedEventAdmin) admin).start();
} catch (Exception e) {
Log.log(Log.ERROR, e.getMessage());
}
}
});
container.connect(id, null);
DistributedEventAdmin works fine, but I am getting the following exception thrown on the call to container.connect() which is preventing the callback to handleServiceEvent of IRemoteServiceListener:

I have dependencies on both SharedObject and RemoteService in my bundle.
Any ideas?
Thanks
