> Hi,
> 
> I would like to request a review for the fix of JDK-8350661. In this fix, we translate the native PKCS 11 error code into an `InvalidAlgorithmParameterException`, as documented in the `KDF::deriveKey` API. With that said, different PKCS 11 libraries may throw different errors and may even (in theory) delay the error until the key is used, as _SunJCE_ does. I believe that this is an improvement but further adjustments may be needed in the future.
