> The `AppStatusListener.getOrCreateStage` method creates a LiveStage object
> with the `info` field set to null and right after that set it to a specific
> StageInfo object. This can lead to a race condition when the `livestages` are
> read in between those calls. This could then lead to a null pointer exception
> in, for instance: `activeStages`.
