Description

I've seen several failures of testKMSProvider, all failed in the following snippet:

        // test rollover draining
        KeyProviderCryptoExtension kpce = KeyProviderCryptoExtension.
            createKeyProviderCryptoExtension(kp);
        .....

        EncryptedKeyVersion ekv1 = kpce.generateEncryptedKey("k6");
        kpce.rollNewVersion("k6");
        EncryptedKeyVersion ekv2 = kpce.generateEncryptedKey("k6");
        Assert.assertNotEquals(ekv1.getEncryptionKeyVersionName(),
            ekv2.getEncryptionKeyVersionName());

with error message

Values should be different. Actual: k6@0
