I believe I do, I've edited java on bytecode level in the past and also worked with unsafe for specific projects to squeeze the most out of them, and I have a hands-on experience with what java can do and how it does it. As for my irrelevant answers thats probably because the content of the topics don't satisfy the low-end of my standards and I don't take them seriously, excuse me for that, that's just me.
Don't blame me for nonsense and locked topics, makes you look stupider than you actually are.
This is no scientific topic neither real professionals/programmers exist on this forum, so proofs are science-fiction, I mainly code in Java and I love it, but at least I accept its cons (fake templates, overheads) and that makes me a better programmer, I use the right tool at the right time, its not just Java
