check if the instance of EventBus is the same. I know you have declared it
as eagerSingleton in your GIN configuration. But do a quick log to see if
the instances are the same.
I remember encountering a similar issue wherein I used to have a new
instance of the EventBus getting injected even though I had a similar
configuration as yours. In order to fix the problem I had to do the
following
1. define a provider
public static class EventBusProvider implements Provider<EventBus> {
private static EventBus bus = null;
/* (non-Javadoc)
* @see com.google.inject.Provider#get()
*/
@Override
public EventBus get() {
if(null == bus)
bus = new SimpleEventBus();
return bus;
}
}
2. bind
bind(EventBus.class).toProvider(EventBusProvider.class).in(Singleton.class);
