  /**
   * A skeletal visitor of types with default behavior appropriate for
   * source versions {@link SourceVersion#RELEASE_9 RELEASE_9} through
   * {@link SourceVersion#RELEASE_14 RELEASE_14}.
   *
-  * <p> <b>WARNING:</b> The {@code TypeVisitor} interface implemented
-  * by this class may have methods added to it in the future to
-  * accommodate new, currently unknown, language structures added to
-  * future versions of the Java&trade; programming language.
-  * Therefore, methods whose names begin with {@code "visit"} may be
-  * added to this class in the future; to avoid incompatibilities,
-  * classes which extend this class should not declare any instance
-  * methods with names beginning with {@code "visit"}.
-  *
-  * <p>When such a new visit method is added, the default
-  * implementation in this class will be to call the {@link
-  * #visitUnknown visitUnknown} method.  A new abstract type visitor
-  * class will also be introduced to correspond to the new language
-  * level; this visitor will have different default behavior for the
-  * visit method in question.  When the new visitor is introduced, all
-  * or portions of this visitor may be deprecated.
-  *
   * @param <R> the return type of this visitor's methods.  Use {@link
   *            Void} for visitors that do not need to return results.
   * @param <P> the type of the additional parameter to this visitor's
   *            methods.  Use {@code Void} for visitors that do not need an
   *            additional parameter.
