Answer 1

Though Guice seems to be very good about using JSR-330 annotations interchangeably, it seems that Multibindings hides the Provider type within a Map and therefore may be expecting to inject a java.util.Map> instead. I haven't been able to reproduce your problem, but try that and see if it helps.

Side note: If you want to avoid changing it in code everywhere, you can hackishly bind a provider of Map> to something that takes in the multibinder-created Map>. If I'm right and this is the problem, you can fix it one place rather than bouncing between javax.inject and com.google.inject everywhere.
