I know a professor who worked on HotSpot Java VM in early 2000s. He is a smart man, but he always makes these false claims how Java will be as fast as C++ the next years. He was the boss of a local Oracle Labs company, though he left that company recently and is now an C# advocate and make similar claims in favor of MS. Such persons are quite annoying as they try to influence a lot of students.
