Ok, I devised a separate service to initiate the in-memory rdf index.
I have my persistent entity store and here is the code I am trying to
run during initialization:
Things are running Ok the first time around (empty entity store). the
next time I run it, I get an exception (below). The code is almost
one-to-one with the code I posted in my previous mail and looks like
this:
class MemoryRepositoryInitializerMixin implements Activatable {
@Service EntityStore entityStore;
@Service private Iterable<EntityStoreListener> listeners;
public void activate() throws Exception
{
List<EntityState> existingStates = new ArrayList<EntityState>();
Iterator<EntityState> temp = entityStore.iterator();
while( temp.hasNext() )
{
EntityState entityState = temp.next();
existingStates.add(entityState);
}
for( EntityStoreListener listener : listeners )
{
listener.notifyChanges( existingStates,
Collections.EMPTY_LIST, Collections.EMPTY_LIST );
}
}
public void passivate() throws Exception
{
}
}
Here is the output:

Why does not JdbmEntityStore know about its content and how would I
explain it to him?
Thanks,
