  /**
   * Helper class to map URL "abbreviations" to real URLs.
   * The default implementation supports the following mappings:
+  * <pre>{@code
   *   ftp.mumble.bar/... => ftp://ftp.mumble.bar/...
   *   gopher.mumble.bar/... => gopher://gopher.mumble.bar/...
   *   other.name.dom/... => http://other.name.dom/...
   *   /foo/... => file:/foo/...
+  * }</pre>
   *
   * Full URLs (those including a protocol name) are passed through unchanged.
   *
   * Subclassers can override or extend this behavior to support different
   * or additional canonicalization policies.
