Description

In geode, cq event for replicated region are cached so that when destroy event comes in, we can just use cached value to determine if a client need the cq event (instead of evaluate the query again for performance).
However, there is a synchronization issue in ServerCQResultsCacheReplicateRegionImpl that could cause geode failed to find the cached event.
