/**
 * The abstract class {@code ContentHandler} is the superclass
 * of all classes that read an {@code Object} from a
 * {@code URLConnection}.
 * <p>
 * An application does not generally call the
 * {@code getContent} method in this class directly. Instead, an
 * application calls the {@code getContent} method in class
 * {@code URL} or in {@code URLConnection}.
 * The application's content handler factory (an instance of a class that
 * implements the interface {@code ContentHandlerFactory} set up by a call to
 * {@link URLConnection#setContentHandlerFactory(ContentHandlerFactory)
 * setContentHandlerFactory} is called with a {@code String} giving the
 * MIME type of the object being received on the socket. The factory returns an
 * instance of a subclass of {@code ContentHandler}, and its
 * {@code getContent} method is called to create the object.
 * <p>
 * If no content handler could be {@linkplain URLConnection#getContent() found},
 * URLConnection will look for a content handler in a user-definable set of places.
 * Users can define a vertical-bar delimited set of class prefixes
 * to search through by defining the <i>{@link java.net.URLConnection#contentPathProp}</i>
 * property. The class name must be of the form:
 * <blockquote>
 *     <i>{package-prefix}.{major}.{minor}</i>
 *     <p>
 *     where <i>{major}.{minor}</i> is formed by taking the
 *     content-type string, replacing all slash characters with a
 *     {@code period} ('.'), and all other non-alphanumeric characters
 *     with the underscore character '{@code _}'. The alphanumeric
 *     characters are specifically the 26 uppercase ASCII letters
 *     '{@code A}' through '{@code Z}', the 26 lowercase ASCII
 *     letters '{@code a}' through '{@code z}', and the 10 ASCII
 *     digits '{@code 0}' through '{@code 9}'.
 *     <p>
 *     e.g.
 *     YoyoDyne.experimental.text.plain
 * </blockquote>
 * If no user-defined content handler is found, then the system
 * tries to load a specific <i>content-type</i> handler from one
 * of the built-in handlers, if one exists.
 * <p>
 * If the loading of the content handler class would be performed by
 * a classloader that is outside of the delegation chain of the caller,
 * the JVM will need the RuntimePermission "getClassLoader".
