+/**
+ * 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.
