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?

[ERROR] Key @com.google.gwt.inject.client.multibindings.Internal 
java.lang.String is Double-bound: Bound at 
com.google.gwt.inject.client.multibindings.BindingRecorder.bindConstant(BindingR

I haven't tried you code but this basic code patch is already covered with test 
cases[1], so I suspect that your reproduce steps are incomplete. Can you find a 
minimal code snippet that reproduces the problem?
