Difference between @Singleton and .asEagerSingleton()

Hello,

I have a project where I see my service is failing to initialise.

I am using dropwizard guicey - but it uses Guice underneath, and my question is specific for Guice because the dependency injection is the theme here.

I am attaching the project in question. So that the issue can be reproduced and seen.

The class - `TheProblemClass` extends `AbstractScheduledService` (Guava) and implements `Managed` interface in Dropwizard.
The idea is that I ought to be able to start/stop the service upon Main server startup and shutdown respectively. Also, I could schedule a periodic call to one of its methods.

Some things I have noticed.

1. When `TheProblemClass` is annotated with `@Singleton` - it is working fine
2. When `TheProblemClass` is NOT annotated with `@Singleton` - it is always hanging.

In my Module - I have bound it as an eager singleton. My understanding was that I only needed to do this in one place. And the rest should be OK. Have I misunderstood how Singleton Annotation and Module Configs are supposed to be working together?
