Hmmm...  Thinking about all this mess of "non-specified" C byte length...

Can JNI actually be implemented on a 16-bit per byte system?
Anybody has a reasonable answer?

To consider:
      5.2.4.2.1  Sizes of integer types <limits.h>

       [#1]  The  values  given below shall be replaced by constant
       expressions  suitable   for   use   in   #if   preprocessing
       directives...
...
         -- number  of  bits for smallest object that is not a bit-
            field (byte)
            CHAR_BIT                         8
...

So, what how would one define "jbyte" on a platform where CHAR_BIT is
defined as 16?  JNI depends on having such a type.
