+/**
+ * The presence of this annotation on a type indicates that the type may be used
+ * with the <a href="http://code.google.com/webtoolkit/">Google Web Toolkit</a>
+ * (GWT). When applied to a method, the return type of the method is GWT
+ * compatible. It's useful to indicate that an instance created by factory
+ * methods has a GWT serializable type. In the following example,
+ *
+ * <pre style="code">
+ * {@literal @}GwtCompatible
+ * class Lists {
+ *   ...
+ *   {@literal @}GwtCompatible(serializable = true)
+ *   static &lt;E> List&lt;E> newArrayList(E... elements) {
+ *     ...
+ *   }
+ * }
+ * </pre>
+ * <p>
+ * The return value of {@code Lists.newArrayList(E[])} has GWT serializable
+ * type. It is also useful in specifying contracts of interface methods. In the
+ * following example,
+ *
+ * <pre style="code">
+ * {@literal @}GwtCompatible
+ * interface ListFactory {
+ *   ...
+ *   {@literal @}GwtCompatible(serializable = true)
+ *   &lt;E> List&lt;E> newArrayList(E... elements);
+ * }
+ * </pre>
+ * <p>
+ * The {@code newArrayList(E[])} method of all implementations of {@code
+ * ListFactory} is expected to return a value with a GWT serializable type.
+ *
+ * <p>
+ * Note that a {@code GwtCompatible} type may have some {@link GwtIncompatible}
+ * methods.
