If you want Map> at the injection point, the way to bind it is:

MapBinder mapbinder = MapBinder.newMapBinder(binder, String.class, Processor.class); mapbinder.addBinding("splineV1Beta").to(SplineProcessor.class); mapbinder.addBinding("invertV1Beta").to(InvertProcessor.class);

You would use toProvider() if you are supplying a custom provider, which you are not, i.e. you are merely trying to use the implicit underlying provider.
