Because Oracle JRE/JDK supports AES-128 out of the box. AES-192 and AES-256
are supported if Java Cryptography Extension (JCE) Unlimited Strength
Jurisdiction Policy Files are installed. In this test case, key size is 256
bits. We should install JCE not only with this test also any test with 192/256
bits key. I commented out this test by default in case this test fails.
