To follow up on my own email to point out some points regarding this
solution that occurred to me after reading the CNI documentation:

On obvious disadvantage of this approach is that it would undermine the
Java==C++ illusion CNI promises.  Calling Java code from separately
compiled C/C++ code wouldn't be possible in a transparent manner.  
However, under normal C calling conventions, calling C/C++ code from 
Java would work fine---which is a common application of gcj, I think.  
The problem of calling Java from C/C++ could be solved by extending CNI, 
by adding the additional parameter manually, or by providing macros that 
would add it.  Unfortunately, none of this is very appealing.
