C++ (as in g++) has compiler support with JNI.  I've been turning the idea
in my head as going down this route with D (gdc) support in the same way
through some sort of magic module which generates these special types
(jint, jclass, etc) - not too different from eg: gcc.builtins module.  But
for the time being at least this is a deferred long-term wish list goal.
