This is not only surprising, but also seems like there might have been some
problem in the way the benchmark behaves.
I have seen better or in the worst-case similar performance after upgrades
from Sun JRE6 to openJDK7

> Sun JDK 6           2h 36m
> OpenJDK 6          3h 24m

> OpenJDK 7          3h 34m
