> 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`.
