I'm not a JNI expert (you are calling from a thread known to the JVM,
right?). However, getBundle is one of the magic methods listed in
section 6 (6-4) of the Java Secure Coding Guidelines that depend upon
the immediate caller. If there isn't an immediate [Java] caller, that
isn't going to work. Which ClassLoader would you want getBundle to use?
