/* the KVJava object has methods implemented as JNI. This file is the Java
 * part of the class, which is compiled as usual with javac, then a
 * C header is generated from it (using javah -jni) for the JNI functions.
 * The implementation of the JNI functions in C is in KVJava.c. This gets
 * built into a shared library (which must be installed to a place the
 * dynamic linker can find it at runtime).
