Hey Mark, Very helpful and well put. My email was far too terse and generic. You're absolutely right; a bug is a bug and an unimplemented feature is still a valid request. It would be bad form to close valid issues. I apologize for my poorly stated message. Your details are spot on for what I

I wonder if in this case the problem is related to branch prediction or instruction re-ordering. The FastMath.pow() method has a lot of ifs to handle special cases, but they are all independent and and handled in sequence. No results are calculated or stored in them, so the JVM might wrongly assum
