/**
 * JNIAdditionalImport is used by the JNI generator to qualify inner types used on JNI methods. Must
 * be used when an inner class is used from a class within the same package. Example:
 *
 * <pre>
 * @JNIAdditionImport(Foo.class)
 * public class Bar {
 *     @CalledByNative static void doSomethingWithInner(Foo.Inner inner) {
 *     ...
 *     }
 * }
 * <pre>
 * <p>
 * Notes:
 * 1) Foo must be in the same package as Bar
 * 2) For classes in different packages, they should be imported as:
 *    import other.package.Foo;
 *    and this annotation should not be used.
