It seems that the AES secret key factory is missing in 1.7 (a known bug ). Since SecretKeySpec extends SecretKey this is easy to get round

Of course you do realize that your Cipher construction defaults to using ECB block mode which is generally considered insecure since it allows splicing of ciphertext to produce valid forged cleartext. You should really use one of the feedback block modes such as CBC.
