Not if the JIT compiler absolutely knows that it can have no effect on
anything other than performance.

Really? I looked at the JITted code with cordbg. Did you?
I tried running your code without the call to Math.Cos, and got the
same results. Did you? Are you saying that Math.Cos calls are
absolutely free?

Whatever you say...

On my box, that shows .NET throwing exceptions to be significantly
slower than Java. Of course, any system which is throwing hundreds of
thousands of exceptions ought to look at its design very carefully
anyway.

There are areas where .NET is faster than Java.
There are areas where Java is faster than .NET.
