> When bucket cache use FileIOEngine, it will rebuild the bucket allocator's
> data structures from a persisted map. So it should first read the map from
> persistence file then use the map to new a BucketAllocator. But now the code
> has wrong sequence in retrieveFromFile() method of BucketCache.java.
> {code}
> BucketAllocator allocator = new BucketAllocator(cacheCapacity,
> bucketSizes, backingMap, realCacheSize);
> backingMap = (ConcurrentHashMap<BlockCacheKey, BucketEntry>)
> ois.readObject();
> {code}
