The thing that's odd is that without the 3rd party DLL present, everything
works just fine.  My JNI functions are called and work (just debug printouts
in that case).  Only when I actually call the 3rd party DLL (and obviously
I'm linking against it), does it fail - and it fails before it even
tries to call
a function - during the loading phase.

I'll go ask there.  Thanks!!!

Good to know.

Thanks!
