Java string objects are not null-terminated, and they are stored in
a Unicode format which must be translated back to the platform's
native encoding before it can be used.

You need a JNI Glue layer to convert your Java objects and primitives

No matter what we think of Linux versus FreeBSD, etc., the one thing I
really like about Linux is that it has Microsoft worried.  Anything
that kicks a monopoly in the pants has got to be good for something.
