> I think the bug is in this code from RegionProvider:
> {code}
> r = cache.getRegion(key.toString());
> if (type == RedisDataType.REDIS_LIST)
> doInitializeList(key, r);
> else if (type == RedisDataType.REDIS_SORTEDSET)
> doInitializeSortedSet(key, r);
> this.regions.put(key, r);
> {code}
> The NPE happens on the last line (the put call) because r is null.
> I think this code just needs to handle the race in which cache.getRegion
> returns null.
