### What problem does this PR solve?

**For example, in the following case, after the FE restarts,
snapshotInfos will become a LinkedHashMap:**

@SerializedName("si")  
private Map<Long, SnapshotInfo> snapshotInfos = Maps.newConcurrentMap();

**The solution is to declare it as ConcurrentMap or, more specifically,
ConcurrentHashMap:**

@SerializedName("si")  
private ConcurrentHashMap<Long, SnapshotInfo> snapshotInfos =
Maps.newConcurrentMap();
