code: @Inject
     public void inject(@ComponentName(ASYNC_OPERATIONS_EXECUTOR) ExecutorService asyncOperationsExecutor) {
        this.asyncScheduler = Schedulers.from(asyncOperationsExecutor);
     }
docs: Injects the cache - unfortunately this cannot be in start. Tests will rewire certain components which will in
  turn reinject the cache, but they won't call the start method! If the latter is fixed we can add this to start
  method and add @Inject to the variable.
