-/**
-  * Indicates whether or not a JDK specific type or package is an
-  * exported part of the JDK suitable for use outside of the JDK
-  * implementation itself.
-  *
-  * This annotation should only be applied to types and packages
-  * <em>outside</em> of the Java SE namespaces of {@code java.*} and
-  * {@code javax.*} packages.  For example, certain portions of {@code
-  * com.sun.*} are official parts of the JDK meant to be generally
-  * usable while other portions of {@code com.sun.*} are not.  This
-  * annotation type allows those portions to be easily and
-  * programmatically distinguished.
-  *
-  * <p>If in one release a type or package is
-  * <code>@Exported(true)</code>, in a subsequent major release such a
-  * type or package can transition to <code>@Exported(false)</code>.
-  *
-  * <p>If a type or package is <code>@Exported(false)</code> in a
-  * release, it may be removed in a subsequent major release.
-  *
-  * <p>If a top-level type has an <code>@Exported</code> annotation,
-  * any nested member types with the top-level type should have an
-  * <code>@Exported</code> annotation with the same value.
-  *
-  * (In exceptional cases, if a nested type is going to be removed
-  * before its enclosing type, the nested type's could be
-  * <code>@Exported(false)</code> while its enclosing type was
-  * <code>@Exported(true)</code>.)
-  *
-  * Likewise, if a package has an <code>@Exported</code> annotation,
-  * top-level types within that package should also have an
-  * <code>@Exported</code> annotation.
-  *
-  * Sometimes a top-level type may have a different
-  * <code>@Exported</code> value than its package.
