I did not understand the specs for JNI in that way!
I interpreted them that you may have (and in reality
will need!) to recompile your native library to fit
to the specific JVM.
Only the API (as text!) is defined in jni.h and
further!

Hope that helps,

P.S. I will check it out sometimes, but I have currently only the JDK
on my machine and no MS JVM (which claims to support JNI).
