-/**
- * 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.
