    1.34 - * The AccessibleObject class is the base class for Field, Method and
    1.35 - * Constructor objects.  It provides the ability to flag a reflected
    1.36 - * object as suppressing default Java language access control checks
    1.37 - * when it is used.  The access checks--for public, default (package)
    1.38 - * access, protected, and private members--are performed when Fields,
    1.39 - * Methods or Constructors are used to set or get fields, to invoke
    1.40 - * methods, or to create and initialize new instances of classes,
    1.41 - * respectively.
    1.42 - *
    1.43 - * <p>Setting the {@code accessible} flag in a reflected object
    1.44 - * permits sophisticated applications with sufficient privilege, such
    1.45 - * as Java Object Serialization or other persistence mechanisms, to
    1.46 - * manipulate objects in a manner that would normally be prohibited.
    1.47 - *
    1.48 - * <p>By default, a reflected object is <em>not</em> accessible.
