> Expire entry event has {{null}} in topology version field (see {{CacheContinuousQueryEntry}} constructor in the {{CacheContinuousQueryManager#onEntryExpired}} method). When Backup acknowledge is sending for such a message it silently (without warnings to log) fails with NPE on {{GridDiscoveryManager#cacheGroupAffinityNodes}} -> {{GridDiscoveryManager#resolveDiscoCache}} for {{null}} topology version (see {{CacheContinuousQueryHandler#sendBackupAcknowledge}}).
> This can lead to leaks in query entries buffer ({{CacheContinuousQueryEventBuffer#backupQ}}).
