Why is Erlang slower than Java?

Why is Erlang slower than Java on all these small math benchmarks?

Despite many answers and interest the question is still open - why?

Erlang HiPE is also compiled to native, compact data types (not min 32/64 bit sizes as in java), no threading overhead (actors)... And still java7 is faster from x10 to x100 in that benchmarks.

Why? dynamic typing, slow GC or poor native compiling?
