C/C++, with the right libraries (Score 1)

C/C++ is faster and more platform-independant than Java, provided you are using good libraries.

Take a look at PTK (the Portable ToolKit). The libraries have a C interface, but also contain glue for full C++ integration. Most importantly, it supports all the standard operating system functionality (everything from file/network access to DLL's to database access to full-blown GUI development) on 13 platforms (including *nix, Windows, and the Macintosh) and 7 hardware architectures.
