  /**
   * Provides a special handling for renaming of serialized classes.
   *
   * <p>Often, as the time goes the serialized classes evolve. They can be moved to new packages,
   * renamed or changed (by a mistake) to not reflect the version of class stored in previous
   * sessions.
   *
   * <p>This method deals with some of this incompatibilites and provides the module owners a way
   * how to fix some of them.
   *
   * <p>When a class is read, the <link>Utilities.translate</link> is consulted to find out what
   * whether the name of the class is listed there and what new value is assigned to it. This allows
   * complete rename of the serialized class. For example: <code>org.netbeans.core.NbMainExplorer
   * </code> can be renamed to <code>org.netbeans.core.ui.NbExp</code> - of course supposing that
   * the new class is able to read the serialized fields of the old one.
   *
   * <p>Another useful feature of this method is the ability to supress wrong <code>serialVersionUID
   * </code>. This was causing us a lot of problems, because people were forgetting to specify the
   * <code>serialVersionUID</code> field in their sources and then it was hard to recover from it.
   * Right now we have a solution: Just use <link>Utilities.translate</link> framework to assing
   * your class <code>org.yourpackage.YourClass</code> the same name as it had e.g. <code>
   * org.yourpackage.YourClass</code>. This will be interpreted by this method as a hit to suppress
   * <code>serialVersionUID</code> and the <code>NbObjectInputStream</code> will ignore its value.
   *
   * <p>Please see <link>Utilities.translate</link> to learn how your module can provide list of
   * classes that changed name or want to suppress <code>serialVersionUID</code>.
