Interesting. Java people have been saying this for years and
it's never been quite true, so I just looked up the benchmark
shootout to see if you're right. It shows Java 7 doing pretty
well against C++ these days, roughly equivalent speed or at
worst half as fast:

[...]
It doesn't do that well when single core is selected (always
slower, 4x worst case):
http://benchmarksgame.alioth.debian.org/u64/benchmark.php?test=all&lang=java&lang2=gpp&data=u64
It means that Java VM/libraries can explore multiple cores
better that C++.
Which in a day and age that you can hardly buy single core
machines, is a big advantage.
