The JNF methods that proxy the JNI methods automatically check for Java exceptions, and rethrow Objective-C exceptions. Plain JNI requires that you always check if a Java exception occurred, and then take some appropriate action (and not call into JNI again until the exception is cleared). JNF_COCOA_ENTER() and JNF_COCOA_EXIT() setup and tear down autorelease pools, and catch Objective-C exceptions and re-throw them back up to Java.

How does one link to JNF?  Under:

/System/Library/Frameworks/JavaVM.framework/Frameworks/ JavaNativeFoundation.framework

Use
-framework JavaNativeFoundation
for more details see man page for ld command.
