Mono Project Wow. "One crazy idea that the team had at that dinner was to translate Android's source code to C#. Android would benefit from C# performance features like structures, P/Invoke, real generics and our more mature runtime. [...] We decided it was crazy enough to try. So we started a small skunkworks project with the goal of doing a machine translation of Android from Java to C#. We called this project XobotOS." Most of Android's layouts and controls are now in C#. The small benchmark is stunning, but as much as I admire the work, I'm wondering that this like going from bad to worse - from Oracle's Java to Microsoft's C#.

RE: Why not just use gcj

It's a mistake to call a JIT an interpreter. Yes, it's possible to interpret bytecode, and that's what Sun's earliest implementations of Java did. But modern JITs will compile bytecode to native code before ever running it (or, in some cases, after it's run more than once). The only difference is that compilation is done when needed rather than ahead-of-time.

There are legitimate issues with JIT compilation strategies. The obvious one is startup time: there's a tradeoff between shorter compilation times and faster code, and so if you have to compile an application every time you run it, then you're going to do less optimization. But it's not interpretation.
