What it's more likely to happen is what gets to be optimized. If something doesn't happen often, it will be slow. This is what JITs do too. DOS attacks have nothing to do with this because they don't affect correctness of the code.

Nothing in those tickets can prove that the JIT doesn’t optimize when there are exceptions. There are other bazillion of things that could be having that effect! we cannot discuss these topics under such conditionals

I don’t, C2 has and can have bugs. But you’re making this statement as if it was fundamental to how it works and therefore the pure FP way should be recommended. And I think there’s nothing fundamental about throwing exceptions and having optimized code!
