Speed. Message passing libs are all about HPC. In a paper I read an MPI
implementation for java was shown to be 10-20 times slower than C. Which
means that you can find a Java MPI implementation but would not really 
be worth using. There are indeed people who do parallel programming with
Java, but as you can guess that serves only pedagogic purposes (from the
viewpoint of HPC), like Java itself (sorry couldn't resist)


Thanks,
