I'm guessing that you have an institutional requirement for using Java
on MP systems.

I've been down that road myself, and like you, I found none of the MPI
wrappers very appealing. There seem to be several initiatives to make
Java better for HPC, but I don;t think any of them are active. Java has
largerly moved into the realm of server-side, web-oriented applications.

Are you locked into Java for entire packages, or can you use a mixed
mdoel with C/C++/Fortran engines wrapped in Java interfaces? I've found
that approach to be rather rewarding.
