It's embarrassing that Fortran got beaten by a very unoptimized Java code. But this is probably not because of Fortran is slow and Java is fast, but because the whole benchmark results are pretty much a coincidence of bad coding and if someone else wrote it, the results could be as well completely reversed. E.g. the Java code uses some of the worst performance antipatterns that are possible to do in Java, e.g. like creating small objects everywhere (Optional), while C++ version uses primitives like ints and bools.
