title: Is there an equivalent to Boost::Python for Java?
body: <p>I've been working with Boost::Python to expose some high-performance code to python recently, and it's just a dream to work with.  I'd like to be able to maintain a single C++ codebase and expose it to Python via Boost, and to Java as well.  I know about JNI, but I was wondering if there's something equivalent to Boost::Python, but targeting Java.</p>
