Problem:
If a user attempts to use a CachingMostRecentProvider to decrypt a record that does contain a mat-desc, but that mat-desc does not contain the key value "amzn-ddb-meta-id," they get an NPE. This can happen if a user tries to encrypt with another one of our providers then decrypt with the CachingMostRecentProvider.
Solution:
Instead, users should get a more friendly error that decryption was unable to succeed.
Out of scope:
The CachingMostRecentProvider is not intended to interoperate with other providers.
