/**
 * This class is for Serializable permissions. A SerializablePermission
 * contains a name (also referred to as a "target name") but
 * no actions list; you either have the named permission
 * or you don't.
 *
 * <P>
 * The target name is the name of the Serializable permission (see below).
 *
 * <P>
 * The following table lists the standard {@code SerializablePermission} target names,
 * and for each provides a description of what the permission allows
 * and a discussion of the risks of granting code the permission.
 *
 * <table class="striped">
 * <caption style="display:none">Permission target name, what the permission allows, and associated risks</caption>
 * <thead>
 * <tr>
 * <th scope="col">Permission Target Name</th>
 * <th scope="col">What the Permission Allows</th>
 * <th scope="col">Risks of Allowing this Permission</th>
 * </tr>
 * </thead>
 * <tbody>
 *
 * <tr>
 *   <th scope="row">enableSubclassImplementation</th>
 *   <td>Subclass implementation of ObjectOutputStream or ObjectInputStream
 * to override the default serialization or deserialization, respectively,
 * of objects</td>
 *   <td>Code can use this to serialize or
 * deserialize classes in a purposefully malfeasant manner. For example,
 * during serialization, malicious code can use this to
 * purposefully store confidential private field data in a way easily accessible
 * to attackers. Or, during deserialization it could, for example, deserialize
 * a class with all its private fields zeroed out.</td>
 * </tr>
 *
 * <tr>
 *   <th scope="row">enableSubstitution</th>
 *   <td>Substitution of one object for another during
 * serialization or deserialization</td>
 *   <td>This is dangerous because malicious code
 * can replace the actual object with one which has incorrect or
 * malignant data.</td>
 * </tr>
 *
 * <tr>
 *   <th scope="row">serialFilter</th>
 *   <td>Setting a filter for ObjectInputStreams.</td>

 *       already established.</td>
