Is there already a way to compute the expression in the subject without the ByteBuffer allocation? I saw quite a few equivalent formulations in the OpenJDK sources, and perhaps it's time to add a standardized solution.
Isn't this really calling for intrinsification of ByteBuffers? With that, C2 would know that the ByteBuffer doesn't escape, and could collapse the lot into a load.
It's a lot of heavy machinery for something that should be quite simple. I also expect quite a few users during VM startup. -- Florian Weimer / Red Hat Product Security
