You can also try deriving the wrap key separately with something like:
KeySpec keySpec = new PBEKeySpec(password.toCharArray(), salt,
ITERATION_COUNT, KEY_LENGTH);
SecretKeyFactory keyFactory = SecretKeyFactory
.getInstance("PBKDF2WithHmacSHA1");
SecretKey key = keyFactory.generateSecret(keySpec);
And initialize the Cipher in WRAP mode with this SecretKey.
