I taught an HPC programming class at my alma mater a few years ago. I used C, as I thought there would be resistance to Fortran (there was). I had people tell me the only programming they had done was in Matlab. And one student was unhappy because he didn't know C, but knew C++ ... Low level interconnect access isn't the only reason why Java isn't in significant use in HPC. I don't expect this development to change the situation much.
