That's what I'm saying.  I think perhaps Java does NOT wrap a null 
exception thrown by JNI code.  Java wraps a null value when you throw it 
from Java, but JNI tends to have a lot of holes, especially if you are 
dealing with "signed" or "trusted" code.  There's ways to get around the 
checks Java does of JNI code in the interest of speed, and if you don't 
check, then you don't get protection.
