[lyiyu66]

Describe the bug commit: 577b87bea7eea93fa1e02305ff2049820d65a30d Cache will not be expired for getMultiVersionMessage().

To Reproduce Steps to reproduce the behavior:

1. Using getMultiVersionMessage() method in sharedLibary feature.
2. Set its cache items to expire with below method:

cacheItem_zhcn.setCacheItem(cacheItem_zhcn.getEtag(), cacheItem_zhcn.getTimestamp(), 0l);
cacheItem_source.setCacheItem(cacheItem_source.getEtag(), cacheItem_source.getTimestamp(), 0l);
cacheItem_en.setCacheItem(cacheItem_en.getEtag(), cacheItem_en.getTimestamp(), 0l);

3. Check the cache whether is expired: cache.getExpiredTime()
4. See error: the cache always not expire

Expected behavior cache should be expired in certain time, then new request will be sent out to service for updated translation.
