You got a point there.

JVM has a ridiculous performance, not fitting for any computationally expensive
operation. At best it's some kind of mudware for data plumbing and
simple network
applications. The memory system, whatever it is doing, is absolutely
terrible. I've
implemented some semi-sophisticated information retrieval code on it
(related to a
search engine) and I've seen that it's not only much slower but
horribly bloated
memory-wise as well. You can only use it for toy problems.

And there are even papers using Java/MPI for high performance computing!
Using Java still turns any computer to a Commodore 64, so why are
people using it?
