Have you considered using a provider? It would be easy to write one that meets your requirements, e.g.:

import com.google.inject.Provider

class RootObjectProvider implements Provider {

    ...

    @Override
    RootObject get() {
        ClassD d = new ClassD( .... );
        ClassB b = new ClassB( ..., d, ...);
        ClassC c = new ClassC( ..., d, ...); // Note that b and c share d.
        return new RootObject(b, c, ...);
    }
}

You can use the provider two ways:

1. Bind it as a provider with either the @Provides interface or the .toProvider() binding decoration.
2. Inject the provider directly and invoke it to create RootObject instances as needed.

Hope that this helps.
