hmmm...
Our code failed the ECB_VT test for keySize > 128.
This is because NIST changed part of Rijndael when promoting it to AES.

Okay my bad I didn't check it... still, could we check our code against
their test vectors anyway? On top of the checks you've already
written...
That might catch things like the infamous encryption bug we had at some
point. (The code was fine on .5, the usecase changed on .7 and it
wasn't anymore)

No,
The code we are using is *not* FIPS-197 compliance. The standard test
vector does not test the use cases we have.

Well then you should be testing it against the live jvm's code and not
some pre-computed value if that's the point...
Anyway I do suggest you check it against known to be good values:

No, it's not from any know reference. I just pick a random key and
plain text, enipher it, get the ciphertext.
I was planning to implement JVM-based AES (bug 2330), this test is
just a casual test to verify the pure java implementation and jvm
implementation matches.

Where did you dig those constants from? presumably FIPS but would you
mind putting a reference in a comment please ?
