Mach-O shared libraries have the file type MH_DYLIB and the .dylib
(dynamic library) suffix and can be linked to with static linker flags.
So, if you have a shared library named libcool.dylib, you can link to
this library by specifying the -lcool flag. Although shared libraries
cannot be loaded dynamically as modules, they can be loaded through the
dyld API (see the manpage for dyld, the dynamic link editor). It is
important to point out that shared libraries cannot be unloaded.
so if your jnilib is dynamic library it can not be unloaded
if your jnilib is a bundle maybe it's possible but I'm not sure

Does anyone know how to do this in Java 2 using a JNI lib on OS X
10.3?
I have a vague memory that native libraries are linked into a JVM on a
class-loader-specific basis, and I have another vague memory that
there is no unload() for native libraries ... So (if those are both
accurate :-) ), I would suggest that you would need to load your app
using a new class loader, and when appropriate create another class
loader so as to reload your code and its supporting native lib...
