Well, most of it is written in Java.  But we use C++ for two main reasons:
access to low-level APIs, and performance.  Sometimes C++ allows you to do
things you cannot conveniently or efficiently do in Java.  CLasspath had
the goal of trying to do as much as possible in Java rather than native code;
the use of CNI makes it convenient to use C++ when appropriate.
