/**
 *  @CalledByNativeUnchecked is used to generate JNI bindings that do not check for exceptions.
 *  It only makes sense to use this annotation on methods that declare a throws... spec.
 *  However, note that the exception received native side maybe an 'unchecked' (RuntimeExpception)
 *  such as NullPointerException, so the native code should differentiate these cases.
 *  Usage of this should be very rare; where possible handle exceptions in the Java side and use a
 *  return value to indicate success / failure.
