> Without invalidateCache, the deleted key may still exists in the servers' key
> cache (CachingKeyProvider in KMSWebApp.java) where the delete key was not
> hit. Client may still be able to access encrypted files by specifying to
> connect to KMS instances with a cached version of the deleted key before the
> cache entry (10 min by default) expired.
