Using GinMapBinder with annotations produces Double-Bound exception

[GoogleCodeExporter]

What steps will reproduce the problem?


Add following binding to bind a Map:

GinMapBinder<String, String> optionsBinder = GinMapBinder
  .newMapBinder(binder(), String.class, String.class,
    Options.class);     optionsBinder.addBinding("scope").toProvider(LoginScopeProvider.class);



What is the expected output? What do you see instead?
