Estou tentando injetar uma variável anotada no escopo REQUEST:

Map<Key<?>, Object> seedMap = ImmutableMap.<Key<?>, Object>builder().
  put(Key.get(String.class, Names.named("name")), name).build();
return ServletScopes.scopeRequest(new InjectingCallable<>(injector, 
  GetModule.class), seedMap).call();

Where, InjectingCallable injeta GetModule dentro do escopo REQUEST:

/**
 * A Callable that is constructed in one scope and injects a Callable into a potentially separate
 * scope.
 * <p/>
 * @param <V> the type of object returned by the Callable
 * @author Gili Tzabari
 */
public final class InjectingCallable<V> implements Callable<V>
{
    private final Injector injector;
    private final Class<? extends Callable<V>> delegate;

    /**
     * Creates a new InjectingCallable.
     * <p/>
     * @param injector the Guice injector
     * @param delegate the class to inject and delegate to
     */
    public InjectingCallable(Injector injector, Class<? extends Callable<V>> delegate)
    {
        Preconditions.checkNotNull(injector, "injector may not be null");
        Preconditions.checkNotNull(delegate, "delegate may not be null");

        this.injector = injector;
        this.delegate = delegate;
    }

    @Override
    public V call() throws Exception
    {
        return injector.getInstance(delegate).call();
    }
}

GetModule é definido da seguinte forma:

@RequestScoped
private static class GetModule implements Callable<Module>
{
    private final String name;
    private final Session session;

    @Inject
    public GetModule(@Named("name") String name, Session session)
    {
        this.name = name;
        this.session = session;
    }
}

Quando executo esse código, recebo este erro:

1) No implementation for java.lang.String annotated with @com.google.inject.name.Named(value=name) was bound.
  while locating java.lang.String annotated with @com.google.inject.name.Named(value=name)

Se eu vincular a mesma variável ao escopo global em que ela funciona. Se eu remover a anotação, ela funcionará. Esse problema parece ser específico para variáveis anotadas no escopo da solicitação. Alguma ideia
