Avoid multiarray allocations in AESCrypt.makeSessionKey

XMLWordPrintable

      One of our services has a hot path with AES/GCM cipher reuse. The JDK code reinitializes the session key on that path, and JDK-8308105 shows up prominently there. Fixing JDK-8308105 would take a while, as would likely require multiple patches in VM internals. Meanwhile, we can avoid the multiarray allocations in AESCrypt.makeSessionKey completely, reaping performance benefits.
