> 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.
