BouncyCastle: java.lang.SecurityException: Unsupported keysize or algorithm

Hi All

I am getting this exception preparing to decrypt a file that is AES encrypted by the JCE. I am using bouncycastle do decrypt it.

java.lang.SecurityException: Unsupported keysize or algorithm parameters

Following the bc docs I installed the unlimited strength policy file jars but I am still getting the error. Is this error thrown if something else is wrong? or is it only thrown when the the install does not offer unlimited strength. BTW this is a 128 aek key.

The code thorws on the init:

Cipher cipher = Cipher.getInstance("AES");

cipher.init(Cipher.DECRYPT_MODE, key);

Thanks for any pointers.
